How do you tell what TB you have? or for that matter, what size it is? the guy i bought this car from said it was a 75mm, but how do i know?

The only sure way I can think of is to take it off and measure (you need to measure on the intake side).

75mm should be alright for your application, IMHO

The cobra inlet opening is 70mm so unless you have it opended up I would just get a 70mm. A 75mm would probably work better but unless you open up the stock 70mm opening to 75mm I doudt you'll reap the benifits of a bigger TB. .02

60mm. The stock one, as well as the aftermarket FRPP one, are easy to recognize. Got pics?

so you're saying that 75 would be pointless? what if that part was also ported? is it possible?

Yes, you can have the intake ported so to match a 75mm throttle body.
