Upgrade a old Jailbroken iPhone 3G

I'm so unhip, my Jailbroken iPhone 3G is at ver. 2.1 . Unsure how best to make it shiny and cool again.
My iPhone 3G has been running the jailbroken 2.1 firmware, as a result of the one and only jailbreak I've done. I don't understand the internals of the process well, let alone the dependencies. Being both a salty, weathered professional in technology, and an utter control-freak, I'm a bit hesitant to just go ahead with some of the instructions I've seen online. Hence, I'm reaching out to the hive mind.
When recently I found that the Facebook app for iPhone won't run on 2.1, I realized I finally have to take the step of continuing with the jailbreaking process. So I'd like to upgrade to 2.2.1, or heck maybe even 3.0. However I haven't found much info out there related to upgrading from such an "old" firmware version.
I've downloaded QuickPwn 2.2.5-2, along with firmware version "iPhone1,2_2.2.1_5H11_Restore.ipsw" and am ready to give it a go .... once I've gotten some reassurance that I'm not jumping too quickly :-)
Subquestion 1: Are there any caveats (esp. related to loss of data - contacts, calendar, etc.) for upgrading from 2.1 directly to 2.2.1 or 3.0, i.e. skipping 2.2 or any other intermediate version? (Note, I am not concerned about the baseband-upgrade caveat; I've no intention of ever unlocking my iphone.)
Subquestion 2: What's the role of iTunes in all this? I'm running 8.0.0.xx ; one document I found indicated that 8.2 is necessary, but another said that this would "break" jailbreaking. (Note, I'm running iTunes on Windows, not Mac.)
Subquestion 3: Does the jailbreaking process require that I first upgrade to the non-jailbroken version of firmware (using iTunes) and *then* install the jailbroken version? Or can I just upgrade from jailbroken-version-2.1 to jailbroken-version-2.2.1_or_3.0 ?
Subquestion 4: Is my understanding correct that, after I've successfully upgraded the iPhone to whichever-version of firmware, that iTunes is then to be used to do a restore of all my data back onto the phone?
Thanks in advance for your help,
Old Wussy Geezer
