Don't feel stupid at all. Have others asked the same questions? Yes. But that's why there are stickies and FAQ threads. But also Member's Rides threads. If you see a car you like while looking around, find their ride thread and see what kind of setup they have and it'llgive you an idea of what to expect.
Throwing full coilovers on a car is easy. Especially if you're running a stock, or close to stock wheel. The only thing you'll have to watch out for is camber/toe alignments and making sure you're not so low that you rub the fenderwells or anything on the underside of your car.
It's not difficult or impossible, obviously. But it's definitely something you want to make sure you're schooled in before diving in.
I've been picking at everyone ones ideas or what they have done.... From dropping my car on one piece to putting camber kit all around so my wheels can sit straight. Change my strut bar and end links... But these rims are the death of me. Thanks for all your help... There's someone on this site with bbs lm wheels... I think his name is emann but he is rolling with 17s and I want my car sitting just like his.... Again thanks for all the info..
