need to move already indexed pages to new URL

I did a few searches on wordtracker.com and found out that by naming my cgi script (part of URL) to a different keyword I could make more money. At least the new keyword is 4-5 times more likely to be found by visitors...according to their calculations.

The problem is that I don't want to lose any visitors in the process. Right now most people are coming from google via http://www.domain.com/relevant-keywo...rms=Store_Name pages. How can I best move those links (as far as google is concerned) to http://www.domain.com/BETTER-keyword...rms=Store_Name ? They are hundreds of those pages, can't redirect them individually.

On my end, all I have to do make another copy of the script and name it, I can have more than one copy too, but I don't Google to penalize me for duplicate pages. I also will change the links on the pages that I have hardcoded the searches (so google indexes them).

Any advice? Also, would Google be nicer need to move already indexed pages to new URL to me if i rewrote the URL /path to html?

thanks in advance....
