There is a bedding tutorial on this site somewhere that I read once. It is actually very well done, and does a really excellent job of describing how to do it yourself.
However, if you aren't good with using tools, or aren't comfortable doing work yourself, I would have a professional do the work. For someone who is a machinist, knife maker, carpenter, or other type of person familiar with doing work with tools, it really isn't all that difficult. I have bedded a number of my rifles myself, and had professionals do other rifles because the rifle was already there for other work. A side benefit of using a good professional, is that they will often educate you about a number of things before doing the work. Often, this education is quite useful.
If you do decide to do it yourself, use lots of release compound. Then use even more release compound. Having a rifle glued into the stock when you didn't plan on that can wreck a stock pretty fast.
