you're dealing with a neglected 22year old truck probably over 200k miles, you should expect issues. fix them, and it will be a very good reliable truck. done this to several, most current is a '97 4Runner (3rd gen) SR5, similar issues but different, over 200k on it, runs like a top
you more than likely DON'T need a starter, you just need starter contacts in the solenoid. $15 in parts from rock auto and ab little over an hour of time. ( have 2 good used 22RE starters I'll sell for reasonable if you're interested, I don't need them anymore as I don't have any trucks with that engine any longer, if nothing else, a good spare isn't a bad thing to have )
Rear axle seal, needs axle bearings, don't just do a seal, the bearing has worn enough that the seal can no longer do its job. the parts aren't stupid expensive ( $60 for the bearing per side, seal is about $8, use good name brand, Timken or BCA ), but you'll need a press and a special ( home made) tool to remove and install the bearings on the axle shaft.
Power steering hose, it is what it is, a 22yo part that lasted far longer than ever expected
as for the CV'S, are they bad because the boots are torn, or are they rattling around dry of lube and the balls have started to come apart ? torn boots, you've got time, and it's still drivable axle shafts aren't terribly expansive ( $50-$70 @ Rockauto.com ) and not too tough to change out
MAF wiring could be fun, if water has gotten inside the MAF, it could be an issue.
Ujoints, grease them, grease the ball joints too
