Are you having a problem with the texture coordinates? The actual texture generation? Or are you using a premade texture? Or do you want to use a set of premade textures? As far as having 1 set of texture coords, thats not a problem. Even if you want to do texture splattering, you don't really need more than one set (just precompute the final texture and as long as your not using dynamic terrain you'll be fine). Theres tons of tutorials out there on this subject (depending on what exactly your problem is as your question isn't that clear, at least to me). Just using Google, the first thing that popped up for me was This.
