I started with the Joyetech eGo C-Twist batteries (variable voltage) and a couple Kanger EVOD tanks, and it worked out great. The Innokin iTaste VV batteries are also a great starter, and both types of batteries have their pros and cons. I went with the Joyetech eGos because they're 1000mAh batteries, which allowed longer time between recharging. The downside to the eGo C-Twists is that the numbers on the voltage dial are really hard to read, but I was okay with that. The iTaste VV's have a bright screen and it's easier to see the voltage adjustments and they allow for wattage adjustment if you prefer, but they're 800mAh so they don't go quite as long before needing to be recharged. It just depends on which tradeoffs you're okay with making. I will say that getting at least two batteries is a really good idea, so you can always have one charging for a quick swap when the other runs out.
There are a lot of generic eGo Twist batteries available at dirt-cheap prices, but I think it's better to go with a name brand (like Joyetech.) I've just seen too many reports of the generics just not working after a few weeks, and the build quality isn't always great. IMHO, spending the extra few dollars for a Joyetech, Innokin or Kanger is money well-spent. For "starter" tanks, I personally think the Kanger EVODs are a great way to go: they're inexpensive (around $4-$5 each) and replacement coils are easy to find. I don't like the dual-coil EVOD 2's, but that's a personal thing and they're cheap enough to try one. The next step up would be something like a ProTank 2, which can be found on sale for around $12: more liquid capacity, a replaceable Pyrex tank and they take the same coil heads as the EVODs. They don't have adjustable airflow, but you can get an adjustable airflow base for a few dollars if you want.
Of course there are a lot of other options, but these worked great for me and seem to be commonly recommended for a good reason. When it comes to juices, that's a personal preference that will require some tasting on your own. A reputable local vape shop is a good place to get starter stuff and try out some juices at the same time. FWIW, I was a pack-and-a-half a day smoker for years and I started at a 18mg nic level: that happened to be perfect for me, but I'd recommend getting a couple small bottles of different nic levels, so you can find one that you prefer. I think it's better to err on the side of a lower nic level, because you can just vape more (instead of making yourself sick with too much nicotine.) Just my personal opinion though.
Anyway, good luck! Vaping has been one of the best things I've ever done for my health, and I wish you the best!
