Simple Question, 3S-GTE, Work on an Auto? Options

[Hym3n]

One very simple question. Does the 3S-GTE engine work on an Automatic? Now, a better question--does it work on an Automatic AT200 (USDM ST)? If not, is it within reason to change the transmission and do whatever else necessary to put a 3S-GTE into the USDM ST? ..if it does require additional modifications (beyond transmission), list what you think should be changed.

For those of you that just love to help us n00bs out:
-What kind of risk will I run using this engine? (i.e.: could some random part blow much easier with this engine?)
-Should I replace anything else in my car after installing this engine?
-What would you recommend doing assuming I had infinite cash and wanted to keep my car a 6GC?

And for those of you that just want to help me out because I'm new to the site:
-How would an Intake/Exhaust upgrade fair against a 3S-GTE upgrade? (I know the price differences, I just want to know hp comparison)
-What brand would you recommend for Intake? (if it's exotic, where can I get it?)
-What EXACTLY is an 'exhaust'.. I mean, (god I hate sounding so stupid, don't ream me too bad..), I'm seeing exhaust manifold, pipe (der der), silencer, etc.. and nothing really makes sense since most of these websites just have part names and prices, no description. What is the part, why am I looking for it, how much should I expect it to run me?
-What risks do I run having installed an Intake/Exhaust? (would it stress any particular part more than intended causing a shorter life span? what parts? why?)
-Any idea on how much my insurance could increase by installing an Intake/Exhaust? A 3S-GTE?
-Does installing a body kit or any other interior/exterior styling component affect insurance rates?

Thanks guys, (don't be too mean, I'm 15 and I guess this is about the only way I have to learn about this stuff..)
