I have always used this for caulk, but anything that is 100% silicone will be fine.
You don't really need the caulk tool, IMO. That tool might not work well for your situation anyway as it is meant for surfaces that meet at 90 degrees, which doesn't quite apply to your situation. All you need to smooth the bead is a wet finger and a bar of soap. Did your finger in water, run it over the soap and then use the finger to smooth the bead. You can do it with just water too. Have a paper towel handy to wipe off the excess from your finger.
I think I get about 40-50 ft with a 3/16 bead out of a 10oz tube, maybe more, maybe less. I would imagine two tubes would do everything. If it were me, I would buy 3 and return the last if I didn't use it - sometimes it is nice to have the extra on hand just in case.
You can use painters tape, but you don't need to IMO. Also, you don't need as much caulk on the bead as you think you do.
Also, unless you intend on caulking a lot more, save some money and get a cheap gun. It will work just fine. All you have to do is remember to hit the back little level to take pressure off the cartridge when you are done running the bead so it doesn't drip. You probably don't even need those caps for storage.
