Aluminum tends to be fairly difficult to torch braze by hand, because the melt temperature of the filler versus what you're trying to bond is typically pretty small. I've been lighting metal on fire for near a decade now, and I wouldn't (and don't) touch aluminum if I don't have to.
Stainless is IMO super easy to braze in comparison, so long as you have a fairly reliable flux. The problem with these bernzomatic torch nozzles you're looking at is they can be somewhat underwhelming in the heating department, and it can take quite awhile to get things to temp, which can overcook your flux and then things oxidize and no filler sticks.
At the sizes you're talking about, the wall thickness would be somewhat important. If your tubing is thick, it could be difficult to braze. If it's fairly thin, you should be able to get it done, and you can clean oxides or extra silver braze with a dremel wheel or sandpaper. I use the dremel wheels.
BAg-7 has a pretty low solidus/liquidus, and should be achievable with the torch. If you want good corrosion resistance, BAg-24 has 2% nickel, but the temps go up a bit. Should still be achievable with this torch. I like boron added flux, I find it is way easier to tell when it activates, because it clarifies.
Not so bad. Depending on how perfect you want it, you might just paint it without sanding. Problem is you CAN'T test the colors they have in stores without buying. You can get an idea from the cap color, but they do have that dark Al / gunmetal color.
If you sand, I like these: https://www.amazon.com/Dremel-511E-Coarse-Finishing-Abrasive/dp/B000FBF3OM/ref=sr_1_10?ie=UTF8&qid=1494880198&sr=8-10&keywords=dremel+sanding
Use blue painters tape to tape off any area you don't want to sand and also to keep the tire clean. I apply the paint with a fine brush, not spray.
I bought a dremmel last year and I use these scuff pads to clean my clubs.... It works really well, but leaves a eggshell finish - http://www.amazon.com/Dremel-511E-Coarse-Finishing-Abrasive/dp/B000FBF3OM/ref=sr_1_13?ie=UTF8&qid=1394972219&sr=8-13&keywords=dremmel+bits
