I'll third the background music. For me, it helps take my brain off of the act of typing, and my fingers just do their thing. Also, I find that looking off, away from the monitor helps, too.
It does take awhile to get used to a mechanical 'board. For years, you train yourself to mash down the keys using rubber domes. The key is to not try to not bottom out, you have to just let it naturally occur. After awhile, you get to really "know" a switch and you subconsciously type lighter. Keep after it. Once you start to really get used to it, you will want to type on nothing else.
