Just to reduce the hassle, I would call the place you're going to take it to for the alignment and ask them what they would charge you to swap them out if you bring the parts in. I wouldn't think they would charge much for that. But either way, you shouldn't have any problems doing it yourself. Refer to this site for guidance, http://www.extremehowto.com/xh/article.asp?article_id=60252 It's got some pretty good info to get you started.
