Lost settings

I just updated to 333 and have a problem with a couple of settings.
My main problem is that i dont remember how i did things in the first place........
Specificaly i had removed the footer from my opening page in 331 and in 333 there it is and i cant remember how i got rid of it in the first place.
Also i had stopped the page title from appearing at the top of the pages and now its back and i cant remem............
So obviously i should write things down..
Is there some kind of simple proceedure to follow when updating themes in order not to lose these changes so i could go back and do it again more correctly.....?
Or else
1...How do i get rid of the footer from the opening page [its not responding to ''the footer in homepages' box in the theme options] ?
2...How do i stop the page title showing up?.....jim
