JQuery UI integration

JQuery UI integration

Hi

I'm starting on a new web application project and I'm looking at using JQuery UI.

What guidelines / recommendations are there for integrating JQuery UI into a web site?

For example ...

- Should / can the JQuery UI css be used for non-JQuery UI elements?
- What about colors and fonts defined in the css. Can those be used by the rest of the web site?
- What about integrating other javascript UI elements such as TinyMCE. Are there guidelines for that?
- How should the web sites css be managed? Should it be kept separate for the JQuery UI css? What about css naming?
- Etc

I'd really appreciate hearing for those with experience using JQuery UI so I don't repeat their mistakes.

Thanks
