Mystique upgrade rearranged things

I had Mystique version 2.7x and was prompted to upgrade to 2.8x, so I did. Now I have several problems I can’t figure out how to resolve.

Here they are in the order of biggest concern:
–My side bar widgets are now showing up at the bottom *
–The header for my site “THE PUPPETEERS OF PUGET SOUND” is too crowded looking**
–The popups (nav icons) for Twitter, RSS and Facebook are missing, though they appear under Mystique > Mystique Nav Icons

https://puppeteersofpugetsound.org is the site.

I’ve also seen advertisement for Mystique 3.1, and I’m unsure if it will solve my problems or make them worse, so I haven’t downloaded it.

* I still see my sidebar things under Widgets as the Primary Sidebar, but don’t get why it is appearing on the bottom instead of the side.

** I’ve tried dickering around with the CSS related to site-title, but am not having much luck

Thanks for any help you can provide.
