Sure, a lot of this is in the form 990 that the Foundation files with the IRS this year. Currently besides me Mark Ghosh and Chele Chiavacci are on the board; Rose Goldman is also in the filing as she helps out with taking notes for the meetings, and coordinating the outside accounting and legal firms that make sure everything is tip-top, but she's not on the board. I don't know exact terms of board membership, my guess would be it's voted on by current directors.

As you can also see from the filings, the Foundation has no employees and pays no one a salary, there are no board expenses or reimbursements. Its only goal is what's state on the Foundation website. Most of the revenue comes from the PBC subsidiary of the Foundation which runs WordCamps, and will have about 4.2M in revenue this year.

It feels like you're looking for more how WordPress is run. (People often confuse the Foundation with WP-the-software and W.org.) Best place for that info is on make/core and here:
