What size esc do i need to run 29t motor @ 7.2v ?

Just about any brushed esc should work

added the 3-1 Planetary Gearbox from injora 35t motor and it slows the truck + overheats on 2s lipo, will this overheat on planetary Gearbox?

Mainly a motor for amateurs it can help you get a hobby started

The product images show that the front (pinion side) of the motor uses a bearing instead of a bushing, is this correct?

Mine did come with bearings. This motor is too high in RPM to use bushings. And honestly I dont know many manufacturers that still use them. Its almost just as cheap to use bearings now.

Will it fit in a carisma f150? Will it make it faster/ more wheel spin?

It’s a brushed motor. Faster/ more power go brushless and Lipo battery
