I need to know what the difference is between Dx10 and Dx11. Are they basically the same or is it a whole new and different Model? I ask this because I just bought a new laptop with the 260m in it and I also qualify for the free upgrade to Windows 7. Will Direct X 11 have new features that my GTX 260m can not use?

You can use DirectX 11 on all DX10 and DX10.1 hardware, and also on various DX9 chips (The so-called 'downlevel' fuctionality).
However, there are some features that will only work on DX11 hardware, such as the tessellator option and the new SM5.0.
Other features, such as multithreaded rendering will work on all hardware, and the new compute shader will work on some DX10 and DX10.1 hardware (as far as I know, CS4.0 will work on all nVidia 8-series and higher, CS4.0 and C4.1 will work on Radeon 4000-series).

So to answer, DX11 will have some features that your GTX260M can use, and some that your GTX260M cannot use.
Regardless of whether you're using DX10 or DX11 though, Windows 7 will improve your 3D performance anyway, because it has a more efficient display driver stack than Vista. Windows 7 will also reduce memory usage, so you'll get more mileage out of the same hardware.

Definitely upgrade to Win7. I'm using the beta right now in both my desktop and laptop and it's way better than Vista.
