Mast
Didn't quite understand what help you are asking for but I will tell you from experience that the mast on the 28.5 is not a lightweight. Are you intending to do it yourself? If so, you will need a crane or some sort of hoisting capability like a gin pole. Really nothing unique about it from any other mast. Connect forestay and two side stays first, then the back stay, then the lowers. Make sure the wiring doesn't get pinched at the step. If you have never done one before, I would hire a yard to do it and be there to watch and learn.What you you can do, and is very impportant, is tune the rig while it is on the ground according to the manual. Instructions can be also found on this site. This can make a big differnce in how the boat sails. Make sure the tension is symetrical from side to side. You should also make sure the steaming and anchor lights are operating before raising the stick. Make sure the lenses are not clouded. If so, replace or try cleaning with toothpaste It is also a good time to check the sheaves for wear along with the halyards. Tighten all hardware. If you are bothered by wiring banging inside the mast, this is a great time to fix that problem with cable ties. Don't forget to put on or retape spreader boots and tape cotter pins. Good luck.
