A few questions on switching from my powermac G5 to a 17" macbook pro

Question

Hi, picking up at used macbook pro on monday(Apple MacBook Pro MA611LL/A 17" Notebook PC (2.33 GHz Intel Core 2 Duo, 2 GB RAM, 160 GB Hard Drive, DVD/CD SuperDrive)
I'm going to use it as my main machine with an external keyboard and mouse hooked up, along with an external 23" cinema display in extended desktop mode. Then when I need to work somewhere else I'll just unplug it and go.
A few questions from a new macbook user:
• What's the best way to migrate all my apps, data, photos, etc. Should I use migration assistant? I'm a web designer with dozens of small apps that I may not have the installers for but would like to do a fresh install of the ones I have like CS3. With migration assistant can I just pick some apps to move over, or do they all move over and does it transfer the registration info in case I misplaced certain serial numbers?
• I'll be selling my desktop, I know you can only install CS3 on one machine, how do I get the CS3 "unactivated" on my Desktop so I can install it on the macbook pro? I own the copy of CS3 and have the dvd's and such.
• I have a TON of Dreamweaver sites defined, whats the simpleist way to transfer the site info over so I don't have to track down all of that ftp info for every site?
• I have over a year of Time Machine backups on my current desktop machine, do I transfer those over somehow so my macbook reads them or is it just better to start over with a fresh time machine backup?
• Will I have any issues with my Iphone or appletv with itunes thinking I'm authorizing a new computer but I'm really only going to be having one machine?
• The person I'm buying it from is doing a clean install of the system, when I get it should I go ahead and do a fresh Leopard install just to make sure its done properly, and if so is there are there "best practices" on doing that?
• Any other tips or advice?
Thanks in advance, I know thats a lot of questions?

While waiting for responses, I came up with this reload script after a little research. The only major problem is that it makes the entire page blink when it reloads. Any thoughts on improving or completely changing it to get rid of the blink and keeping everything efficient?
