Best practices UI/UX workflow with Adobe Products?

Illustrator+Photoshop is a good combo, but only for visual side of your project. For UI/UX design and mocups it's not so good. There are more effective software for this. Here is good list of UI/UX design tools, that you can use depending on your operating system. Indesign is good for mocups. Adobe Fireworks is good for designing layouts.

I can't say that anything will be better than using a direct Illustrator->Wireframe mock export (which Illustrator can do) but, considering the modern web, you may want to take an honest look at Dreamweaver's own built in rapid prototyping.

Here's the front page and a 3 minute video going over the process:

The main benefit here is we're always trying to tear down the walls between "the design department has dropped off some pretty pictures, now we actually need to make it". That keeps design perhaps a bit too separate. I like hybrid design/dev UI/UX developers who can actually use tools that both help them rapid prototype, but also drop off something the development team can actually use to produce the design. Not every project will run like this but getting a designer used to development constraints has always been a goal on mine so they understand why their design can't just: "[insert something silly]". They'll know why, and not to do it in the first place.

If you can, give it a try and you may find that although you're no longer in pixel or vector land, dragging boxes and pictures around (based on code under the hood) isn't too hard and can save your developers quite a bit of time. $0.02

I think it depends on what you're most comfortable using.

When I think of UI/UX, I tend to think in terms of image sprites.  I'm not sure how well MU handles that. Maybe somebody else knows.

I would probably use Dreamweaver or Brackets.
