That battery is an LG HE4 it's a 20amp cell with 2500mah capacity.
Because your mod is regulated and has safety features, you don't need to worry too much about ohms law. If you decide someday to use an unregulated mod then you will need to worry about that stuff. If you stay under 130w you won't stress the batteries and you will be vaping in RELATIVE safety. The thing you do need to be cautious of more than anything is the condition of your batteries and their wrappers. This isn't something to be careless with. Using damaged cells is probably the most dangerous thing you can do with your new mod.
Since you appear to only have 1 pair of batteries, I suggest that you order some battery wraps online. They are dirt cheap and if you have them on hand you won't be tempted to use batteries with a torn wrapper.
As far as how to set up your tank, there is a ton of info on youtube on how to build your first coils and how to mount them. Here's a link to a high quality (but long) video on how to build your first coil
Here is a link to a Manta RTA review where he builds and wicks it
If you don't have some already you are going to need some cotton to wick. It's best to use cotton bacon, organic japanese cotton pads, ko gen do cotton, etc. but if you don't have access to vape supplies then cotton balls will work.
I can't really tell you what to build for a coil because I don't know what you have available to wrap the coils on. If I tell you a 3mm inner diameter coil with x wraps is best and you don't have a screwdriver with a 3mm shaft, it won't be much help. Use steam engine
http://www.steam-engine.org/wirewiz.html to make your coil on paper before you actually wrap it so that you can make sure it will be functional. Whatever it tells you the resistance is on steam engine, you will want to half it because you will be using 2 coils in your manta. It looks like you have 24g N80 so I would suggest something around 3mm inner diameter with 5-7 wraps.
If you are going to be using rebuildable atomizers and building your own coils you are going to need to learn this stuff though. This is just to help you get vaping. I also suggest that you get some thinner wire if you like a cool vape. If you could get some 26g and 28g it would be easier to dial it in how you like.
