Heading to her in the morning for tracing..hunting..confusion!
As a foot note, I'm assuming you've done some sort of marine survey and sea trial before purchase. Very important before heading out into uncertain weather and unfamiliar waters. Did notice in your pics the absence of an anchor, the most important system on the boat. You need to test it before heading out just to make sure it is in good working order and that you know how to use it. You just never know.
Engine runs well, hopefully. If it stops en-route, the anchor will help protect you and the boat from any hazards, at least until a rescue boat arrives to offer assistance. Sails need some sort of breeze to move the boat along, so time to check the rigging, related sheets, clutches, winches, etc. in the event you find them handy making speed over ground without the pesky engine noise.
Depending upon the amount of time you want to take getting home, slowing things down a bit, La conner, midway down the ditch, offers a very nice layover. Kingston, across Admiralty Inlet from Edmonds, is another nice layover place heading south.
On the other hand if you choose coming down Admiralty Inlet, as suggested by John, that involves a different sail plan than here. Lots of choices.
