This is pretty easy to do with a profile op. After setting up your profile/levels etc. click the Technology tab and you will see an area called Modify where you can choose which side of the contour line to place your tool. Click the Geometry button next to it to open more options. The one you need to play around with is the modify Offset figure. You can use a neg or pos offset. Be sure to click apply to all to set the offset and it will show you a little hint to see if you went the right way. This area is also great for extending your contours to allow for a lead in/out.
Pockets are even easier. Again on the Technology tab look at Offsets on the right side of the window. Just set your Wall offsets to whatever you want. I think -1 would cut an oversize pocket and +1 would be undersize.
Hope that is clear for you.
