Tower is a nice plus.
Don't worry 'bout the teak. The swim platform on my '00 230VRS was about the same and it came back nicely with a little work and some good teak oil. Plenty of posts on refurbishing them if you search.
The raw-water pickup is under your trailer bunk. I usually wait 'till the back of the boat starts floating a bit at the launch ramp before starting the engine just to be on the safe side. You can't use a fake-lake, but you can install a hose fitting if you really want to run the boat on the trailer.
Guide poles: There are 2 stainless bolts per side that hold 'em to the trailer mount underneath the fiberglass. Use a 1/2- or 9/16-inch wrench (can't remember). Usually the bolts come loose and they just rotate, so check before you go trying to bend them back.
