FB Design Problems and General Question

I am having a couple of problems making design changes to a very simple FB generated form, which can be seen at test1.php. I also have a general question.

First problem: Can't get FB to generate a smaller font size; it always generates 15 pixels. In the main Edit Design window, I tried setting the font size to 10 pixels but it won't generate it for the labels, at least. (BTW, setting a different font family name and color here work fine.) If I go back into FB it shows a value of 10 pixels. To work around this, I have to manually go into the form after generating the form via FB and set the label size to 10 as can be seen for the Name label. Although, I do see that the random question is 10 pixels. So, maybe I'm not setting it in the right place? Also, when I do make further changes to the form using FB, it will regenerate all the labels to 15 pixels and therefore overwrite any labels that I had changed to 10 pixels.

Second problem: Even though I set the Textarea Form Element width to 325 pixels and height to 75 pixels, it won't generate to those specifications. Likewise, if I set the width for the Text Form Element to 325, it won't generate that width either. That is, in the form I have online, both field width for both of these should be the same width and the height of the Textarea field should be shorter but they have not changed. The values in FB indicate they are 325 and 75.

General question: If I am generating a form in a two column page, should I specify a smaller form width? That is, should I change the default value of 850 to something smaller like the width of the area where I am placing the form?

Thanks in advance for any advice.
