Seriously, did you just pull all of this out of your ass hoping nobody would call you out on it? You couldn't be more wrong on most of your points here.
As for team attendance, MLS averaged 15,504 fans per game in the 2006 season, led by Los Angeles' mark of 20,814 per game (sorry for the formatting):

Each team has a salary cap of approx. $1.2 million, but the new "Beckham Rule" allows a team to acquire one designated player whose salary does not count against the cap. MLS pays $400,000 of said player's salary per year, with the team responsible for the rest (have no idea where this mythical $286,000 figure came from).
MLS just signed a new deal with the ESPN networks for a rights fee in the neighborhood of $50 million (something the NHL couldn't do) to show one game per week on their new "Soccer Thursday" showcase. ABC will show the All-Star Game and MLS Cup (and likely Beckham's first match).
The 51% of each team being owned by MLS is patently false. Have no idea where you came up with that.
Each team is owned and run by individual owners and entities. MLS controls player allocations and transfers, but they certainly don't own teams.
I won't even comment on your "72nd best league" comment. Laughable.
