Will the new SIM card = a new number?

Also, how do I transfer all of my apps, contacts, and all other data from my 3G iPhone to my 3GS iPhone?

Simply swap your SIM from your 3G to your 3GS. That will bring over contacts, etc.

Sync your 3GS in iTunes and it should bring everything else bac.

There is nothing special about your SIM. Your number can be tied to your new SIM.

Make sure you have all your contacts on your computer. When you get the new phone just sync them from your computer to your phone.

No, it won't. The iPhone doesn't store contacts on the SIM. Keep all data on the computer and then the iPhone and iTunes will handle the transfer of the number.
 
It depends on how the phone was activated. If it was activated with new sim card, then your existing sim card will no longer work, and the one that comes with the new phone will.
 
not on the sim

Make sure you do a complete backup on your computer.

When the new 3GS arrives you sync via iTunes and your data loads.

This is going to be a little ridiculous to ask, but on my computer there are already a bunch of contacts in my address book because I changed all the screen names on my buddy list on iChat to peoples actual names which creates each of them as a contact in address book. I don't want these contacts to sync over to my phone. How do I sync only the contacts from my phone to my comp and no vice-versa.

Also when I get my new phone how do I sync only the contacts I want over, can I create a list and just sync that list?
