Racing Seats & Rims

Im struggling to buy these two things.
I am a new Celica owner and yes I am only 16.

I want to get black racing seats but I do not know what fits or how to go about buying one. So help would be appreciated.

Secondly, I want new rims. they have to be 15In and on the cheap side. Black,pink, silver doesn't matter. Links would be nice. Thanks Toyota Family!

My Celica is a 2000 Silver Gt. Stock Everything 4cl. 15 inch rims.
