The carpet shouldn't be to bad. If you have a heated garage or a way to warm the carpet up it will help it to conform to the floor pan easier.
Recovering the seats isn't to bad if you take your time.You basically have to break them down and take off any hardware,then there are hog rings and metal bars in the seat foam that the hog rings clip to.
Remove all of the hog rings and peel the cover off as you go. We have upholstery kits complete with hog rings and pliers.Here's a link to them on our site.Not sure if you have a TA or Camaro.
