A bunch of 300ex problems

Just have been having a bunch of problems with my bike lately and wanna see if you guys can help me out, it’s a 2001 300ex with almost no upgrades aside from some cosmetic stuff, new bearing carrier, chain, sprockets, and air filter. So to start while riding last weekend my quad would go maybe 1/8 of a mile then start bogging and die, I know exactly what the problem is because I had this problem before. It has a metal gas tank and apparently every so often it would accumulate flakes of rust at the bottom and in the petcock, I cleaned it out last time but this time the flakes of rust were all inside the petcock almost to a dirt making the fuel flow to only a drip so it would fill the bowl, use all the fuel in the bowl, then die. I fixed that. Next problem was oil leaking out of the head, and onto the header and block, I really loaded the hondabond on this time and even put it on the part where the bolts seat, got every orifice on the head loaded with it. Hopefully that’ll be fixed we will see next time I ride, along with that I adjusted the valves, still tick like crazy even tho they are as to spec as I could get them .005 exhaust .004 intake, I’m thinking at this point it’s worn cam or rockers or maybe cam chain, not sure. Anyway another problem is my skid plate is pretty badly bent and has been bent this way since I got it, the kid before must have really nailed something hard to break the bracket and bend it this much, refer to picture 1. It hits the chain and is kind of annoying especially in videos, how can I bend back the metal? It’s pretty good solid steel, I tried heating the bracket with a propane torch for around 5 mins then pounded it with a hammer and it hardly moved, so I don’t have enough heat, should I just get a new one or is there a way I can bend this back? Next problem is my bearing carrier is moving around, side to side, the axle is in there pretty good but the entire unit is moving side to side. The lock nut doesn’t seem to extend far enough to tighten it up, I’m kind of lost on this one refer to next couple pictures. Last problem is I can’t seem to shift smoothly and I roll in gear, this seems like the clutch cable just needs to be adjusted but I tried adjusting it and can’t get it right, can I just adjust the clutch at the handlebar or should I do the lower part too?
