0-60

I have a 2001 Celica GT. I always thought it's 0-60 was around 6.5-7.1 and after making my account on here this site says its 8.7. That just seems insanely slow.
What options do I have to cut that time down? Anything in the upper 6 range would satisfy me. I've heard cold air Intakes can make a car faster. Is this true?
I don't know much about cars. I want to start learning, though.
Primarily I'm asking what are the first things I would want to do to make my car faster? And what price am I looking at for these?
