Make sure you get a tank with high pressure output, then just screw it on and go shoot stuff.

Rather the opposite - less drop-off than before.

The only caveat to HPA is with RT, but if you don't have RT, then it's just plug 'n play.

Also go for a tank with a good reg.  I like Crossfire and Pure Energy.  I have heard Crossfire is better because the recharge rate is supposed to be better.

DO NOT USE PETROLIUM BASED LUBRICANT on the valve pin of the air tank as this will make your HPA tank EXPLODE in a fiery ball of flame.

HPA is not R/T friendly

dont need Expansion Chamber..  some people do have a second regulator, or stabalizer

Tank cover if you get Fiber Wrapped Tank

Very valid points, but I'd like to elaborate as to why the tank would 'splode. When you compress air to (hypothetically) 4500 PSI into a space of 68 cubic inches, the process generates a great deal of heat. You can actually feel the tank heat up as it's filled. Anyway, in some cases, the heat was enough to ignite any petroleum based oil within the tank (it got there when oil was applied to the fill nipple or valve pin), and the resulting fire blew the tanks. 2.25 tons of air pressure + a fireball inside a tank = bad mojo. It's safe to say you probably don't want this to happen.

To the contrary, HPA is very RT friendly, but it does require some extra work.  With HPA you can unload your RT without fear of freeze.  This is good.

But HPA tanks put out lower pressure than a full CO2 tank, which makes it harder to find and hold the sweet spot.  This can be overcome with tweaking and practice, and is ultimately well worth it.
