The first thing to do is if you dont already know how to black and inlet get a book or a friend that does and learn more kit guns have been spoiled by bad inletting than any thing else. Personally I dont put all that work in on a kit mostly because the wood in them sucks, you can get some decent wood some times but only on occasion.
If you do get some decent wood look up trminic acid [been used to bring out the stripes in tiger stripe maple and birds eye for hundreds of year] read up on these things and on hand shapeing wood before you start, be very precise on the position of trigger ,lock and nipple so you dont have to tear back into it after you finish. The kits mentioned by Cayquad and Gotbuck are among the best, and if you have never built a rifle from scratch then a kit is a good way to learn. Lee
