You're right about the angle of the tube. I try to roll my wrist as I work up the tube so that the arc is perpendicular, but that's difficult at best and often impossible.
Torch argon comes come my handy-dandy Lincoln welding calculator. What value do you use when welding stainless tube (.049 or .065)?

Yep. Small tube welding is definetely an aquired skill, no matter what process is used. Stick is the worst.
I flow 15cfh at the torch, but that's with a #8-#10 cup. Cup size makes a difference here. (My girlfriend taught me that.
)
For back gas, I generally flow 5cfh. The way I do it is set my regulator to like 30-40cfh, and I have a ball valve at the end of my purge hose. That way you can go WOT with the ball valve and fill the weldment quickly, then back it off and watch the regulator until it hits 5cfh.-Matt
