Short rows are not difficult at all. Basically, you are knitting up to a certain point on your row and then turning your work as if you had come to the end and working your way back across the row. With circular knitting you would be treating your work as if it were flat for the rows that require you to work short rows. You knit across the number of stitches as required in your pattern, turn and purl across the number of stitches as required in the pattern until you have to turn your work again. When the short row shaping is done you will knit to the end of your round and start knitting in the round again.
Here's a few good resources on short row knitting:

Also, just FYI, you shouldn't post your email address in a public forum. I have a feeling the mods will delete it eventually but it is really not a good idea. There are too many crazies around willing to fill up your email with junk.
