The best setup is always the one that works best for you. The mini pros are good tanks and should work fine on that battery. You will like the VV it will allow you to vary the voltage and get more "Vapor" If you are getting "smoke" something is burning. LOL
Flavors. Well of course I'm going to recommend mine. When it comes to E-Liquid cheap is usually not good. A fair price for 30mls is between $15-$20 per bottle. You will find most of your better tasting E-Liquids in this range, some a little more, some a little less.
At the moment my best sellers are:
PBFB (Peanut Butter Fudge Brownie)
Hydra's Delight
Watermelon
Buttered Popcorn
Strawberry
Strawberry Waffle
and others
When ever you are buying E-Liquid from anyone you should try and get a sample size typically 4ml, 5ml, or 10ml sizes. This way you are not spending a lot and can try many flavors. There are several companies, including mine, that do -0-mg of NIC, but many do not. Before you buy, check the options and make you can get what you are looking at in -0- nic.
