fixing up the crown vic to sell or keep

ok, im fixnig up my vic to sell or keep if no one buys it by winter

this is whats wrong, and i wanna keep it as cheap and driveway mechanic friendly and know what i would need for each

first..valve cover gaskets..tryd to fix before..but leaks even more now (any help on how to do this? i hate having to replace a valuable peice but not being able to reach it)

wheel bearing (im suspecting) is goin bad, because it squeels and squeeks

im thinkn my brake pads needa be replaced because it squeels when i put on the brakes

replacing a snapped e-brake cable

tranny shakes violently at shift points

moving shift points so there not on 45 and 55 (right where i press the pedal to keep the speed up it shifts, then upshifts after a second becuase its goin too fast)

and the engine is running REALLY hot..drove it home (about 20 minutes) at about 6..and its still hot now..its been 2 hours..and the hood is almost too hot to touch after driving it like that (temp gauge is reading alil above half and just replaced thermostat)

and make last, make it so the car doesnt havta be on to pop the trunk

so anyhelp would be greatly appriciated
