Welcome to playing bass!
I hope you enjoy getting your first bass and amp.
for looking for an amp. Try and get something that is atleast 100 or 200 watts. These will hold up with a loud drummer usually. If you can get one with a balanced out that would be very helpful for gigging in the future.
So try and find a combo
personally I would go with a GK mb combo. the 12 is $340 which is $40 over but it a nice combo. The 15 is $400. if you are getting a 5 string bass the 15 would be recommended, but if you are playing 4 string the 12 is probably fine. They have good tone and a nice growl. They also definitely hold their own.
Look also at ampeg, Peavey, etc....
check Craigs!!!
get a bass used you will get better for cheaper.
I bought a bass a couple weeks ago (for an orphanage in Central America) for $175 that came with strap locks, $30 new strings, really nice pickups, and $100 case. That bass isn't too much worse than mine which is $700.
Hope you can find some gear for cheap. let us know what you find. have fuiun finding you sound and your gear :-)
if you have any questions let just ask someone here will know :-)
again welcome!

shalom,
