You won't miss Notepad++ with Gedit unless you are using it as an IDE.
Streaming is a PITA, but you can check out Kazam Screencaster, which will also beat out Fraps. You can also use ffmpeg if you don't mind command line instead of GUI. For MS Office, you have LibreOffice which saves to and reads all MS Office file formats. The Adobe Creative Suite is going to be a hard one, there IS Inkscape, which is a vector-based graphics program much like Impress, but it uses a different mindset with respect to hotkeys, so it might be counter-intuitive for you to use. As a vector-based graphics program, I feel it to be inherently superior to Viso, however LibreOffice has a program called LibreDraw that does much the same thing. Minecraft has no problems, of course, being a Java program. I'm running TS3 no problems on Mint 15. Filezilla works natively in Mint 15. Quicken can be run in Wine or Crossover, but GNUCash also has a double-accounting system which can read the same formats. There are other options as well you might want to look into.
In other words, about the only problems you will have will be duplicating Visual Studio and Adobe Creative Suite. Unless you do Visual Studio professionally, however, you will no longer need to use it as you will no longer be running in a Windows environment. For Creative Suite, you can try using GIMP, Blender, Inkscape, and a few others that you can google around for (and once you find alternatives, they'll likely be in the repositories), however be advised that all the controls are going to be different than what you are used to, so your training will likely be working against you when working with them. Unfortunately, Adobe CS is one of the few software suites which has extreme difficulties porting over.
