One thing though, you say you want to run the Windows applications that you own. This is one of those things that may or may not work depending on your application. However, you'll find many suitable replacements (most if not all are free) within the Mint repository.
You might want to start with a Live CD so you can play around with it to make sure your computer runs correctly and has all the drivers before committing to installing it.
Good luck and welcome.
