I happened to notice you are a newcomer to DD, and first wanted to welcome you to our little community on the web!

As for your question, I know in my area the baseline for executive level admins is 65wpm, and that's about where my skillset is.
Something that helped me tremendously was message board posting. Granted, I've been an internet message board junkie for a couple years.... but frequently posting things on message boards has taken me from a hunt and peck while looking at your hands (30wpm) to full focus on the screen in front of me, and no need to look at my hands at all (and 65wpm).
Some suggestions are to practice at home, by typing out all your correspondance to friends, making to-do and grocery lists on the computer and etc.
If nothing else, just practice, practice, practice
