Does it gradually lose it's power?

Nothing. Still Black. Still a Hole. All the stuff is just part of the singularity now.

Black holes just sit there then as a large mass in that area of the inverse. There are though to be supermassive black holes at the center of every galaxy functioning as the gravitational axis on which everything spins.
Black holes are not statis structures though. They emit significant amounts of radiation, known as Hawking radiation, and blast antimatter away from each of its poles. In this way, black holes dissipate energy in the form of this radiation and actually evaporate over time.
So after the black hole has sucked in everything within its effective gravitational influence, it will just evaporate over time.

When the very last black hole finally gobbles up the last of all the other black holes it will explode and everything will start over again.
This is, of course, pure speculation and it could just as easily be argued that it would eventually dissipate (or evaporate) by slowly releasing small amounts of "Hawking radiation" (also see http://casa.colorado.edu/~ajsh/hawk.html ).

How many silly answers!
First, Hawking radiation is not the same with Xrays we see at BH's poles. Xrays and other high energy particles are produced when the matter speeding up around the BH. Part of that matter is swallowed by BH, part of it is ejected.
Now, Hawking radiation means that 2 particles are created in BH's neighbourhood (one particle and one antiparticle), and one of them falls into BH and other not. So, the BH lose gravitational energy (cause the energy materialize into those particles). So, it is slowly evaporate.
Now, when a BH has no matter left around her, it can begin to evaporate. To do that, the BH temperature must be higher than the temperature around. Bigger BH is, smaller is it's temperature.
(a very very very resuming answer...)

It has nightmares while it sleeps.
It slowly 'evaporates' according to Hawking. The smaller it gets, the hotter and faster it shrinks.
However, super massive black holes will last for billions of years.

Still it remains as black hole. Mass is higher. Infact the gravity increases due to added mass.

It takes some alka seltzer.
No, really, it doesn't really do anything except perhaps very slowely evaporate due to Hawking Radiation

the black hole sits there with enormous gravitational pul just to pull other things which might come close to it

it just sits there and wait till something else happens to get into range

Nothing happens 2 it.... It jus stays there....... like b4..... As a black hole...!!!
