On your list of things to do, I'm not sure why you want to install a tie-bar. The Prowler comes with a liquid tie-bar and has the centering valve under the hatch in between the motors (unless your boat did not but I thought all did). If your motors are not holding position, you have a problem with your hydraulic cylinders. Fill up the system and purge it, and then watch the motor well for 2 - 3 weeks. If you see oil dripping from your cylinders (a pool underneath), your end seals may need replacing. If no oil leaks and your motors will not hold position, then the inside seal is bad on one or both so you will need to replace the bad cylinder(s).
Best advice is to add a 2nd bilge pump to each side.
AGM batteries are great. Go with 3, and have the house on an AVR/switch combo.
To repair the fiberglass leading edges of the sponsons, the resin that Prowler used was a vinylester so either a similar vinylester or non-blushing epoxy resin is probably the right stuff. Prowler used VE Cook Composite gel coat as well so if you can find someone to mix you a quart of matching gel coat, you can use it to make the leading edges look nice and then have some left over to touch up dings and drill holes etc. Just keep the gel coat in the freezer and it will last a year or two.
I also pulled the stock electronics door out of the console, and using a black starboard section as the base, flush mounted my electronics within the opening (the black starboard covers the opening). That way I could get a 12" Garmin (bigger screen for older eyes). I give up locking my electronics, but I keep the boat behind locked doors.
I cut out the bait doors on top of the rear bulkhead to the full interior dimension, gelcoated the raw esdges after finishing smooth, and installed starboard doors/covers using the same HW that came with the bait doors. That way I turned a pretty much useless space (5" x 9") opening into two areas where I can store 3-3700 size tackle boxes.
I took out the liner in the leaning post as well which again opened up additional space for storage, but I think you have a different type of leaning post from mine (my cushion flips forward).
I replaced the spreader light with one of the Coastal Night Light spreader lights as well.
