Dropping the tank

Alright, so next on my list is dropping the fuel tank. I need to do so to install a new sender for my aftermarket fuel gauge. I've got new straps, and a new snap ring, as well as new line (although it's just the one size-I now know there are multiple sizes)

First question, what's the best way to come at this? I'm not sure how full the tank is, but dad swears it's close to full (he drove it last)

Second, is it worth going ahead and moving the tank over to allow for possibly dual exhaust....
