I've got the MVP 2 and one thing I'd like to point out is if you decide to start dripping and sub-ohming (building coils below 1 ohm) the MVP 2 won't run below 1 Ohm, so you'd have to get a different mod then. Judging from your questions tho, I'm assuming you're pretty new to vaping and you'd probably want to stay away from sub-ohming for a good while as there are some dangers in it.
As far as vaping on a clearomizer, the MVP 2 is amazing. I've used it with the iClear 30, iClear X.I, Protank 2 and 3, Aspire Nautilus, and various disposable cartomizers. The coils have ranged from 1.6 Ohms up to 2.8 Ohms and all have hit beautifully. If you're looking to get a new tank too, I'd suggest the Nautilus, it's 5ml tank will keep you going for days, even a week depending on how much you vape a day. It also hits better than any of the others IMO.
Assuming you get a VV or VW mod, be sure to look up a vaping power chart so you can make sure you're not powering it too high or too low. Too high and you'll burn the cotton or burn out the coils, too low and you won't get a good vape off it. Also, if you're gonna be vaping any fluid with more than 50% VG, turn the volts up a bit more than normal to be able to fully vaporize the thicker fluid.
