My Lion issues

I don't game much, so no advice there. You can delete Safari plugins from /Library/Internet Plug-Ins or extensions from ~/Library/Safari/Extensions
Temps are up from SL.
I had to download apps from 10.4 individually not the all at once button.

 

Spotlight's all done reindexing your hard drive? That used a fair amount of processor on my Mac after the install, and generally slowed things down a little.

 

What he said. Is Spotlight done re-indexing? After Spotlight re-indexed my Startup disk, WoW is way faster than Snow Leopard was on my end.

 

Click the Spotlight icon, or look for the dot in the middle of it. Indexing, oddly enough made my GPU climb as well (OpenCL??)

 

There is a small dot in the middle of the spotlight. Plus clicking spotlight says it is being indexed and gives an ETA on when it is done.

 

Try using the Activity Monitor app. Set it to show All Processes and then sort the % CPU column downwards. If it's spotlight, you'll see spotlight or mdworker Process Names towards the top.

 

From everything I read prior to the release Lion just runs hotter. I never checked my temps but I don't doubt what I have read. I happen to use a Belkin laptop support with a fan blowing on my laptop so I don't notice it much.
