jailbreaking allows for patching the firmware so that it can be unlocked (and unofficial apps). it's not like other phones where you just punch in a code.
Not concerned about the warranty being void (good excuse to get a 3GS!). Just want to be sure I have everything working. If I jailbreak and unlock, will my current SIM card still work? Or do I need to wait until I want to install the new SIM?
your current sim will continue to work. you just get the ability to use other sims too.
that should be fine. jailbreaking 3.01 is slightly trickier because you need 3.0 as well (at least until they update the tool).
also, don't upgrade to 3.1 (yet) or you risk losing the ability to unlock. a future tool will support upgrading to 3.1 and maintain the ability to unlock but it has not yet been released.
Use redsn0w or Pwnage Tool 3.0?
redsn0w is basically plug and go, it's very easy. pwnage is the power user tool for generating a custom jailbroken firmware package which is then flashed normally from itunes. after jailbreaking it, you'll need to install ultrasn0w.
