As others have said, lots of options
I'm in the camp favouring keeping it modest to start with - the approch you have will, i'm sure, result in you buying more stuff later, but a couple of good small batteries won't be redundant if you upgrade to a mod later, as they'll still serve you well for out and about.
I also like the Innokin products, and have an itaste VV V3.0, which has variable wattage and voltage and an ohm checker - there are bigger and better amongst the Innokin and other brands, but I've often thought about getting a mod and come to the conclusion I really don't need one yet. I also have 5 decent eGo batteries of various sizes - from a tiny 350mAh for discreet vaping in shops, pubs and planes to a 1300mAh, and including an 1100mAh VV - I use all of them.
With a good VW battery, you have control and reliability and then you can make your decision about the light sabre when you have a better idea of what features are most important to you.
On tanks/atties - there's a wide range - so I'd suggest getting one of each type to try out, then you can explore more of the style you like best - so that would be a BCC (bottom coil, such as Evod and the range of Protanks), top coil (amongst the better out there are the iclear 16s & 30s - I wouldn't bother with CE4), then there's the DCT (with a carto in a tank) - nice warm thick vape, and maybe even a dripper (just got my first and loving the flavour and vapour)
Have a try of everything - you can't have too many tanks!! (I have 45!)
