You have less than 6 months with a boat, whole new animal, think about it this way, when you went from the bank to the Yak you were looking at bass fishing backwards, throwing towards the bank instead of away from it, took time to adjust I expect, it'll take time to learn a boat too.
As far as baits, I have thousands, if not 10's of thousands tied up in baits, and sometimes that leads to analysis paralysis, or the temptation to change baits every 10 casts, I have begun to restrict myself to 5 or 6 baits when I go fishing, 3 or 4 that I expect to be useful, and a wildcard just in case I blew it with my predicted conditions (i.e expected wind and can see my reflection etc) truth is I have caught more fish this year than last because of it, I'm forced to be thorough, and to cover the available water multiple times, with multiple retrieves in different ways, if I play the game long enough, and the bass haven't gone deep, I WILL get bit, the question is am I willing to work at the puzzle long enough. If it helps, my frogs have been turned in for cigar baits and poppers, my bottom baits are my terminal box (t rig, c rig, ned rig, drop shot, wacky rigs) and a jig box, and the three moving baits I bring are my squarebills, my lipless, and my spinnerbaits...they are all doing work at one point or another.
