So far no bad advice, so you're probably going to get hooked up pretty well.
The reason I'm posting is to highlight a few things that, as a new player (or soon-to-be) you should know. Many of these things I myself have learned by doing them wrong, and having the TB collective (or other sources) bail me out.
1) Practice is practice. There's no substitute or shortcut, and you will suck. Just hang in there.
2) There is no "best" anything. There are higher quality things, more popular things, and more expensive things, and often what you LIKE is none of them. It's OK. If you like the way a bass feels, it is good. If you like the way an amp, pedal, type of string, or pickup sounds, it is good.
3) Watts ratings are, unfortunately, the standard way amps are classified. There can be vastly different amounts of volume put out by amps rated to have the same power. Speaker efficiency (dB), and cone surface area (the size and number of speakers) can make drastic differences in volume. Adding speakers (see #4) is the best way to get louder.
4) Learn about ohms (Ω

. For the most part, bass speaker cabinets come in 8Ω and 4Ω, and bass amps like to see these "loads". When you are connecting amps and cabinets, more cabinets make the ohms go LOWER. Two 8Ω cabinets will show your amp 4Ω. Not many amps like to be used below 4Ω. Adding anything to a 4Ω load will drop the total amp load below 4Ω. It gets way more complicated, and tricky, but that's a good basic overview. Most manufactured products will use parallel connectors and the math as I've shown applies. This means that even hooking up a cabinet FROM another cabinet will still drop the Ohm load. Read the stickies for more detailed information.
5) When the time comes that you find yourself wanting to play with other musicians, it is likely that a practice amp will not be enough. This will be especially true if you intend on playing with live acoustic drums. The frequencies where the bass guitar lives don't like to play nice with small speakers, and require more power to reproduce at louder volumes. A 20 or 30 watt guitar amplifier (music genre and playing style are factors, too) is perfectly capable of burying a bass through a 50 watt 1x10 combo amp, and even more easily if there are drums involved as well.
6) When shopping for bigger, more giggable (or band practice-able) gear, the speaker cabinet is every bit as important as the amp. More cones equals more volume. Bigger cones equal more volume as well, but not necessarily deeper bass; that is a function of speaker and cabinet design.
7) HAVE FUN, DO WHAT YOU ENJOY, and IF YOU LIKE IT, IT IS GOOD.
