I think my biggest tip is to manage your expectations. What you are attempting is not the same as simply moving to a new version of Windows -- literally everything will be different. You've spent a lifetime learning how to perform all these tasks until they became second-nature, but now you plan to move to a whole new system. Thing will be in different places, the way you tweak settings or access content will be different, and it's going to be very frustrating because hey, this task should be easy. Don't expect to cram all those years of experience into re-learning a new system in a few weeks.
The good news is that there's a huge support community, and just about anything you want to do has already been asked and can be found through a quick search. Stick with it, and you'll discover that linux actually gives you quite a lot more control over what you can do with your hardware (not to mention nearly all the software is free). It won't be long before you're asking how you ever survived without many of these tools.
