For Shame!
3 pages already and no-one is being honest with the youngster...
Where is the cautionary note that a bass guitar is nothing more than the physical representation of a vow of celibacy?
And if we can't talk him out of it, we can at least prep him for the harsh realities of being a bass player, things that took us most of our careers to learn, like "When in doubt, fire the drummer, then rage quit." or "Leave the switch on pre- until the sound engineer goes to his desk, then flip it to post."



In all seriousness though,
I am going to give the advice you should be getting, some of it has been covered.
On basses, amps, cabinets - None of us are equipped with your ears. Play everything you can get your paws on, then select the one within your means that sounded/felt best to you. By all means ask questions, but make your own decisions.
This place is great, but it sucks - we're all a little fixated on gear, maybe too much so. Yeah a rig and a bass are the price of entry, but staying is more a product of you, not your gear. It's a poor workman who blames his tools, but it's a far worse workman who expects his tools to make up for his shortcomings. Talkbass emphatically is not a substitute for practicebass...
