If I were you, I would go to the local parts store, get plugs, wires, cap, rotor, and fuel filter first. Then you can go looking for some nicer wheels with better tires. I would also look into getting that tie rod fixed, then an alignment. last thing you want is A) flying out of control on the highway cause your tie rod went out B) your new tires wearing badly cause of a bad alignment. SO with that said, I would probably get the tie rod/alignment done first, then the tune up parts (that part can be done within an hour) THEN get your wheels/tires. How bad are your tires anyways? if need be, I have a couple 4x100 tarantulas with decent tread you can slap on your front to hold you over until you get better tires.
And as far as your clutch letting out high, try adjusting your clutch cable some, if it doesn't work out, you'll probably need to do a clutch job. I can show you how as I am doing one right now if you wanna swing by sometime.
