1) Take it to a bike shop and let them fix it. This will cost maybe $50

For the same $50, you can buy a new bike of
equivelant quality at Wal Mart or Target or
some such store. It will be terrible, but
no worse than the Murray.

What did you do to "get them free" and what exactly do you mean by the gears
being "frozen"?

are the derailleurs not moving or are the shifters themselves locked up?

i would do some research and try swapping out the cables first. When you are
in the internals of the shifters and derailleurs, clean them out and
regrease/oil them.

a simple websearch brought up this:

IIRC, most gripshift units are similar in cable replacement.

you can also replace the gripshifts with new 6/7 speed units found on ebay.
If you can't find them there I have an old set of 7 speed ones you can have
for a couple bucks + shipping.

new cables and housing should cost you in the neigborhood of $10. I would
wager your bike isn't worth much more than that so don't spend too much
money on it (def not a $50 tune up or anything like that). You can always
ride it as a fixie.
