@gtg Ok there is a lot here but Ill try to keep this simple (yeah right). I race and cruise my wing keel and have for a number of year now. I am by no means the leader in the racing field but have learned quite a bit from the Nationals regattas and talking to various sail makers over the years.
1. Yes your bottom needs to be cleaned. Put on a swim suit, grab a scotch brite pad and get to work. If you cant swim use a pressure washer to clean all you can while it on your lift in the pictures.
2. Get that rudder down! 2 inches is huge and will cause significant weather helm. Racing boats add up to a 1 inch shim to the upper gudgeon to get the leading edge more vertical. Class rules state it cannot go under the transom but you want it to be straight. So crank down that bolt or do what you have to do. Most racers use a fixed blade to prevent the folding back as well.
3. C22s are notorious for weather helm not lee helm. I have sailed on a number over the last 29 years for both racing and cruising and never been on a single one that had lee helm but I suppose it is possible. None the less this is not something I would immediately chase out until the rig is properly tuned
4. Rig tune. North sails and the C22 manual have great tuning guides. Hopefully you have an adjustable backstay because to race you'll want one. With the backstay off the side stays on my rig start at 18-20 on a loose gauge and then go up to about 25 as the wind gets above 18kts. The rake is set somewhere between 9-13 inches as she floats on the water. Wing keels tend to want a bit more rake as they fight a bit more weather helm and I need to fight heel as well to prevent side slippage. Forestay at nose height should have almost 1 foot of side to side play with the backstay off. This feels loose like a hobie but allows you to really power up the headsail in lighter winds. As the wind increases then pull on the backstay. The boat is a masthead rig so the backstay does little to adjust rake. Setting the rake is mostly the job of the lower stays. The forwards I believe on mine start at 10-12 or something like that and the aft just sung. Yes all stays go slack on the leeward side. In this tuning configuration beware of mast pumping (shaking back and forth) if this happens stop and tighten the rig. Do not let the mast pump or you'll de-mast the boat before too long as it will stress the spreader joint and through bolt.
5. Sails. I hate to be the barer of bad news but those sails don't look right or "crisp" to my eye form the pictures in the slip. Its hard to judge though based on a no wind situation. Better to get some pictures from another boat while your racing. To point you'll need inside tracks so that the headsail can be trimmed into the spreaders. using your outside tracks will cost you 5 or so deg of pointing which is huge for VMG. Test it out by adding a barber hauler and going for a race. I did this with a line rigged to a cabin top cleat for a few races and was sold that inside tracks were necessary. Your Genoa should come to within an inch or two of the top of the mast and back to the rear window corner or so on the cabin. when fully sheeted in the sail should be within a few inches of the spreader tips. Use a bowman as your sail has no window and it can be difficult to see. Bumper boats are no fun. Also going downwind you'll need a proper whisker pole to hold that head sail out. This boat is headsail driven. All your power and point is in the headsail. The main is just for balance. Make sure you have the proper controls for the main (vang, main sheet, outhaul with purchase, downhaul, loose reefing lines if installed etc.) and read up on sail trim. Find the leader and follow them. What he or she does you do. watch their trim and copy it. Make small adjustments and you'll speed up. Ask if another racer will run Race Qs or a similar app on their phone as you race and compare the data. it will show you tacking angles, VMG, and why you fell behind. Best of all it's free (though the website is a bit our of date).
Once you have a handle on the first 5 steps then comes the fun of fine tuning your rig and climbing your way though the fleet. Please note though that all the above advice is given assuming the following:
you don't have a soft deck
your standing and running rigging is in great shape (no burrs, likely replaced in the last 5 years or less if in the water etc.)
your running rigging is in good shape
You are willing to stress the boat properly for racing (many casual sailors are afraid to truly run the boat)
you have proper understanding of sail trim, draft, and all controls
your keel pin, cable, etc. is in good working order (it will see lift just like the sails and will be loaded more than a day sail during the race)
and whatever else I forgot...
At the end of the day racing is about time in the boat. I race a Laser when I am not racing my C22 to keep my skills up. You can read all the books you want but nothing replaces time on the water and in the boat. Every boat is different (even in a OD class) and knowing your boat will make you a better / faster sailor.
If your around Arkansas in a couple weeks well be racing the Catalina 22 Naitonals again on Degrey lake and you should come by. You'll learn more in a couple days at an event like this than in a couple months of reading and online forums I promise. In fact I almost guarantee someone will take you onboard their boat and walk you thought what works and what does not work.
PS: I sent you a PM if you have other questions.

For reference we caught and passed the boat ahead of us in this shot downwind before the bottom mark. Weight forward on the downwind!
