Answer 1

I strongly recommend this upgrade guide from Turnkey - worked perfectly for me.

Please don't expect that everything works or looks the same once you've upgraded to Magento 1.7. Depending on what features or extensions you use, quite a bit of work might be needed until you're done. So don't do this on your live system. Better duplicate it to a development environment and test the upgrade there.
