The Cabela's kits are ok, but they invariably have the wrong size/type guides for best performance from the blank. They also usually have the incorrect reelseat size, usually to small so the rod will be uncomfortable over a long day fishing.
Best to get on www.rodbuilding.org, with the specifics, such as your reel model and size, species fish, etc. and they'll assist you in selecting the right components. There are many tutorials and library articles that you can access there, or others will steer you to.
Don't be afraid to start with the blank, etc. you want right off. There is nothing you're going to do that can't be done again, just take your time and look to the little details as you go and it will end up as nice as any rod on the store rack if not a little better.
If it was rocket science, I for one wouldn't be able to do it. My first rod was a nice G Loomis that I still use to this day.
