Teri,
Try several events with a couple of trails, if you can. I fish Walleye Tournaments (a lot fewer now than in the past) which are usually "team" events, even when they are Pro-Am draw formats. Each circuit has some pluses and minuses. So, before you decide you do or don't like tournament fishing you need to give it as much of a chance as possible. Everybody doesn't like the same thing, so what works for you will probably be something you don't necessarily try out as your first circuit.
Do what you can to talk to several people who have fished the trail you are trying out. I'm not that crazy about what happens over on the Bash-Fishing Home Page, but I would suggest you post over there looking for folks willing to talk to you about the trail. Get several opinions. And, do be aware that each trail usually has it's own "culture"... So, don't be surprised if a suggestion for one trail is not made for another.
Some things to be tuned in on are 1) the amount of gear you bring as a Co-angler 2) provisions for food/drinks, cooler, etc. 3)always have rain gear... When you are a co it is good to have like Frogg Toggs or other suitable "packable" gear if the weather conditions (usually temps) make them a suitable choice... 4) sunglasses, lip balm, sunscreen, bug spray/wipes 5) I don't know about Bass events, but in the Walleye World the non-boater usually offers $20-40 to the boater for gas (and for us live bait...LOL) 6) Be prepared to be very flexible about the day.... By that I mean, don't expect to make friends and then if you do, great, but don't let a grumpy bad attitude by the baoter ruin your day 7) Be spot on about rules, limits and those matters... carry the written ones if you can 8) Arrive early to meet the boater the day of the event. In your case state exactly what your qualifications and experience levl is a) fishing and b) hasndling a boat/trailer... (some boaters will want you to drive the truck at the ramp, others may not...ask/offer 9) For the safety of both of you, make sure you know where all of the safety gear is in the boat ASAP 10) Respect the boater's boat and equipment even better than you would your own (some folks are very anal, very)
That is by far not an extensive list of thiungs, just some that come to mind.
I have been fishing walleye tournaments from 20 years and I still get surprised, so don't be embarassed to ask questions or be offended if you get "reprimanded".
Good luck.
