Clutch going in the 2.7

Like the title says, I'm getting a clutch soon and putting it in my truck. I've never done this before. I've pulled the motor and worked on it before so I figure if I can do that I can put a clutch in.

I went to my local Toyota dealer and got a clutch disc, pressure plate, throwout bearing, and pilot bushing priced at $380ish. I feel like that's pretty steep. Does anyone have any advice on buying clutches, etc? Aren't there kits you can buy? And does anyone have advice for getting it aligned properly?
