Great questions and welcome aboard!
Google search the forums is the best resource that I've found. For instance: arbitration site:whatifsports(dot)com/forums
Chances are any question you have has been asked a few times before.
Finding a good league can be a trial and error process. The best leagues are the ones that only have 3 or so owners leave a season and have a diverse list of championship winners. If you see one or two teams winning all the titles (look in the league almanac page) I would avoid that league.
Also, a league is only as good as its commish. Good commish's work on recruiting before the season ends (checking in on who's returning as the regular season winds down, getting ads up in the forums early, working on world swaps, etc). The other big role a commish needs to be good at is squashing any shenanigans (arguments on the world chat that get out of hand, extremely lopsided trades that cause other owners to leave, screening potential owners for suspicious activity/reputation.
As far as finding a team, the best teams to pick up have low payrolls and a at least one or two building block prospects in the minors (if you want to build a team from the ground up). That vast majority of teams that come available are either in their twilight years of contending or just mediocre managed teams that never really managed acquire any good assets and/or overpaid for mediocre guys in FA. That said, it doesn't take too many seasons to get these types of teams into a good rebuilding position as long as you're okay paying $20-25 a season. I wouldn't worry about finding the perfect first team IMO, and rather use your first team to learn the ropes (if you enjoy HBD, you're gonna pick up more teams down the road).
Hope some of this helps!
