SEO and Ads plugins for Buddypress

Hi there, I just became a member last week and I'm loving it! I'm very, very new at this, however, thanks to your detailed installation instructions, I've had no issues whatsoever. Thank you!! I do have a couple of questions:

1. Is there a plugin you could recommend that would allow me to place ads on the sides of the site? I would like a similar look to the ads on the left hand side at "We Heart This" at weheartthis.com. How can I achieve that?

2. I couldn't find an SEO plugin compatible with buddypress on your list of plugins. Did I miss it?

Thanks again!!
