Yes I forgot the ohm meter, if you use a multimeter remember to check the resistance of the leads, this is easy to do just touch the probes together for a few seconds, mine have a 0.3 ohm resistance.
Get yourself a coil jig, buy some wire, and check out some of the posts on VT. First you have to know what you want as far as coils go, and start from there.

If it's good flavor and vapor, you're good to go. If it's lacking, bump up the temp, not the wattage.
Just remember if you put a different tank on it you may have to switch modes to power mode instead of temp control mode. (some modern mods switch automatically)
