I know a fair amount about electricity, including all the things you listed. However, I don't have access to an ohmmeter, voltmeter, or ammeter atm.
The first thing I would do, before you use this setup, is get a DMM then. It doesn't have to be an expensive one, just one that you can read resistance and voltage reliably with.
If you build a dead short to the battery, this is a dangerous setup. This is one of the drawbacks to a mechanical (I use them, and my favorite one is my Nemesis). With a dead short or a very low sub-ohm setup, you will draw too much current from the battery. This can cause it to heat up, go critical, and vent (creating a very unhappy situation). You also do not want to over discharge the battery. There is no safety circuitry in a mech, so you can completely discharge the battery and ruin it. I like to check my battery as it comes off the charger (4.20 volts, that battery can safely handle 4.25 volts on a charge), and I like to recharge at 3.5 volts (some like to go lower, but I think the general consensus is absolutely do not go below 3.2-3.3 volts).
When you are starting out with this setup, check the voltage output of the battery often. Eventually you will get a feel for when the battery has discharged to the point it needs to be recharged, but start out checking very often.
Also, read a bit about mechanicals if you have not already so you know if something is going wrong. Above all else, if something doesn't feel right, stop immediately and remove the battery.
