Too many choices is not such a bad thing as it provides some inspiration for which one to do next as these things are like Pringles, you can't stop at one.

Suggest a bolt on neck first up as that is one less thing to worry about and once you have conquered that you can move on to doing a set neck.

Tele's are easy and only tricky bit is shaping the headstock. If you can afford it I would highly recommend the bone nut & neck setup by DB and the PBG shop also has a price for shaping headstock too.
