You might want to slow down with the forum comments unless they are all quality content.
If they are all quality keep building them at the same velocity as they should all be decent links and drive traffic/rankings over time. If you have that many links to your site already 10-30 is not an outlandish amount.
If you can afford it publish a cheap press release. I know at least one vendor in the marketplace will do one for 19 bucks.
I think part of all the google dance is to try and scare seo people into stopping what they are doing.
One month in it very normal after starting to link build to see a drop before the rise... That being said if you have been slightly spammy with your forum commenting definitely slow down

Goodluck and come back and update us after rankings change again! That way we can all understand the big G a little better.
Google is always changing so your case study is very valuable and extremely relative.
How old is your site ?
