I am new to the game as well. Just got my first custom rig (well, semi anyway...the action is a savage and though it isn't full race BR it was all I could and would be able to afford and be able to shoot with any sort of regularity). You don't need unlimited funds, but a steady flow is necessary. If you want to be competitive you need a solid platform to start with, and then lots of practice. If you haven't bought any equipment yet...don't. Go to a match as mentioned and check out the possibilities. The guys shoot a wide variety of rests/bags, rifles, stocks, etc...They all feel different to different people, and before you invest in a $720 farley, make sure it's the right one.
If you are like me I don't have unlimited funds, but this is the sport (shooting in general) that I enjoy and have chosen to put my money toward.
If you want to truly be competitive you have to be able to practice a lot, be able to experiment with barrels, bullets, powder charges, and be ready to change your equipment as your stye/preferences become more apparent (at least so I've read).
You can start with as humble a setup as is available and as long as you have fun, you can always save up for the next level.
As far as people helping you, most of the time you just need to ask. Most benchresters I've met have been more than willing to share if you show that you are genuinely interested.
HTH,
Mike
