1) Rating field : the rating field is a radio button. I would like to change these to stars. Is it possible to do that?
also, the rating field in the user profile for some reason can be rated by the user. Is there a way to just change this to allow visitors/ registered users to rate the supplier.
The rating field is supposed to be stars unless you've some sort of CSS conflict preventing it from loading in the images properly. The rating field has 2 versions "My Rating" and "Your Rating". The "Your Rating" I believe is the one you're wanting that allows others to rate you, but not your self.
2) Image: the profile gallery functionality provided in CB is awesome!!. However,the image is rather small. Is there any function which could launch another window/ mouse over zoom which could zoom in on the image?
Images maybe small due to your resize configuration. Please see profile gallery tab within CB > Tab Management for configuration. The default behavior pops up in a new window. There's also lightbox pop up, which can be configured from the profile gallery tab edit in backend.
3) I am facing issues with PMS. it does not seem to appear at all under the profile.
The PMS plugin is just a bridge for UddeIM. You need to have UddeIM installed first before it'll do anything. Nothing shows on profile except a link to PM a user on the CB Menu.
