Your 2" focuser will come with the adapter for your 1.25" eyepieces.
Basically, for most typical eyepieces of focal length 18mm or smaller, they will show all that can be shown in 1.25" barrel size (except for the expensive 100 degree Field of view ones).
2" eyepieces are good because they will show bigger fields of view when you have 20mm or bigger ultrawide angle eyepieces, or 40mm super wide angle eyepieces. People like the bigger fields of view, because they're nice, and they are good when they frame a really big deep sky object into the entire field.
