You can instead create a static page that will show up under the "Help" box on the left side, you've done this before since you have "Member Benefits" and at least one other page you've added or modified.
ie: Create a static page labeled "What's my size?"
Then you can change the label from "Help" to "Info" or something like that. In your product descriptions you can tell customers to "Click on "What's my size?" button on the left side if you are unsure of your size," or something similar.
This would help you do what you want and leave the speed bar as-is, and no coding is to the speed bar is required.
There's lots of good articles/posts about doing static pages on the site and in the manual already, and I was able to create one with this info (It looks very crude: I must learn a more HTML), but it works like a champ.
Note that when changing the label the "Help" is located in two places that I found: The Label you see on the main store page as the title to the box, plus another if you click on the word "Help" itself in that same box; it takes you to the "Help" zone. You want to change that label also.
By the way cool site
