Welcome Ty!
The above is great advice especially the guitarist teaching bass advice.
In addition to formal training, the following are suggestions:
Learn(by ear or sheet music) from bassists who have gone before. Recordings of James Jamerson(
http://www.ricksuchow.com/press.html), Ray Brown(
http://en.wikipedia.org/wiki/Ray_Brown_(musician) ), Bob Moore(
http://www.myspace.com/bobmooremusic), and hundreds of others help you develop a great sense of timing, feel, and expand your musical knowledge and the role bassists have served. The "place" of a bassist is usually the glue of a song although it can also be forefront(RUSH). Your choice although mostly determined by musical setting you are in.
Learn music YOU like whether it is country, disco, metal, trance, pop, gospel, anything. It is your time(limited resource in life) and life.
Learn odd, humorous bass fun for and entertainment(

Learn "covers".

The ultimate goal, IMO, of ear training yourself is to allow you to play anything you hear(in your head or with your ears). It also allows you to play songs "on the fly"(example: in a band setting a song is called out you've never played BUT you can hear it/remember it in your head). Keeps you sharp and allows you to play music without being stuck on tabs or sheet music. Written music has its place and so does playing without it.
Above all, HAVE FUN.
Music is an amazing gift and pleasure.
Treasure it, keep the passion for it alive, and it will keep you company for life.
Again, Welcome TY!
PS: Read this and understand it. GREAT advice. The rest of the article is at the link.
"When you go on a gig, you have to remember that it's a privilege to play any kind of music -- even sitting in your house by yourself. Music is this wonderful, universal language. It's meditative and spiritual. A lot of people get caught up in the frustrations, and they lose it, the way a preacher loses the calling. When you pick up an instrument, realize how blessed you are. It doesn't matter whether you're playing for 50,000 people or by yourself. I'm not saying I'm a guru of this stuff. It's just that when I pick up a bass, I'm conscious of how much it has given me, and I try to take that onstage with me wherever I go." http://www.ricksuchow.com/press-group-80.html
