Depending on the model of that bass, that can be a anywhere between a 450.00 and 850.00 bass! That's some dime! Congrats.
Re: the amp, you might want to consider something around 100 watts. Like an Acoustic B100. They are fairly inexpensive, make great practice amps, and will handle most small venues, like clubs and such, with ease. There a ton of stuff out there though .. When you go shopping for an amp, bring YOUR axe with you.
look on line, too. Musician's Friend, The Guitar Center, the guitar store, eBay, Basstalk, are good sources for used equipment in good condition, too.
Keep me updated!
