I can't help you with their bubble bath or gel, but I use their M&P soap base which is SFIC. Very good soap base IMO If you decide to try them, check out their Cedarwood Amber FO....to die for!!! HTH
I've used the Goat's Milk Multi-base from here. You can make it as thick or thin as you want by adding distilled water. http://thescentshack.com/catalog/index.php?cPath=31&osCsid=e0326e96ee9ca15ec62762e1373828aa and I think KB sells it too, but not sure. HTH
Sounds like you need to spend some time reading the board. There is enough reading material here to fill 6 months time. Start with the very first thread of this catagory "Helpfull links for Newbies".

Cruise through the craft stores Tucker (I hope you have them). They are a dime a dozen. If you can't find them....pm me after the holidays and I'll buy a bunch and send them up to ya!
If I splash wax on a portion that I don't want it on I zap it with the heat gun. If your real careful you can "move" it slightly or all the way down to where the other wax is. HTH
