Linux alternative to Macromedia?

Does anyone know some good open source Linux alternatives to the Macromedia Studio bundle (Flash, Dreamweaver, Fireworks, ect.)?

Will my Applications Run in Linux?

Anyone know if my applications will run if I switch to Linux?

I do alot of web design so I need to run Photoshop, Dreamweaver, Flash, Fireworks etc.

Please help me out on this one!
