General Layout Questions

You can use CSS to redefine the .small class if you want but I would suggest viewing the markup, finding the input ID and targeting it individually and resizing it rather than changing a global class setting.

You can find samples of targeting form elements for CSS manipulation here..

The current version of the plugin doesn't have an option to change the description placement, but the 1.6 Release Candidate version is available now and that option has been added. You can choose to have the description above or below the inputs. It's a global option though so it would apply to all the descriptions in your form, not just for one field type.

The description placement option is in the first panel with the individual form settings.

The markup doesn't "reside" anywhere that you can edit it. It's built dynamically by the application. The "triangles" you're seeing are most likely background images being applied to the list structure that contains the form elements. You can reference this FAQ item for a way to override the theme styles.

Nah, the option isn't in the radio buttons box. It only exists in the main form settings panel and it applies to the entire form. You either select labels above for the entire form, or labels below. You don't define them per each field.

Glad the bullet fix worked too. It's a fairly common thing and that CSS snippet usually takes care of it.
