Your setup gear is fine. Your nicotine strength is appropriate.
Your Protank will need replacement coil heads for when your flavors start to taste muted or burnt, or when the vapor production falls off. These should be available from where you purchased your Protank, or can be ordered online from most e-cig vendor websites, or local B&M vape shops. Cost is around $3 each. Expect to change out new coil heads every 1 - 3 weeks.
Have a backup for every part of your setup. You can't vape if you don't have a charged battery, a working tank, or no juice. Don't give yourself an excuse to buy more cigarettes because you can't vape.
YouTube will become your friend and educational resource. Do searches for whatever equipment you may have a question about. PBusardo is a well-known reviewer of e-cigarette gear and juice flavors.
You may find it necessary to experiment with different types of clearomizers/clearotanks should you find the Protank not to be to your liking. Preference from one model to another varies from one vaper to another.

Experimenting with different e-liquid flavors makes vaping fun. The suggestion for sample packs from different vendors that offer them is a good one; you won't waste money on larger bottles of juice that you may end up not liking. If there are local vape shops which offer a juice tasting bar/station, take advantage of this to sample before you buy.
Know that most of the nicotine in vapor is absorbed in the mouth, throat, and nasal passageways, not in the lungs. Your vape technique may need to be different than your smoking technique. Imagine sucking on a straw in a thick milkshake. Use your cheek muscles to draw in a mouthful of vapor, hold it for a second, then inhale. Long, gentle draws are better than short hard draws.
Drink plenty of water; e-liquids can dehydrate you slightly, and a dry mouth will affect your ability to taste your flavors. Exhale some of your vapor through your nose, as your sense of smell assists your sense of taste. Your sense of taste has been damaged from years of smoking; this will improve the longer you are totally off of cigarettes.
It sounds like you are off to a pretty good start. You have a support system here at ECF to answer all of your questions.
