How is a 'handset wipe' done?
Here's the important bits on the GT540 for resetting:
http://www.howtoreset.com/LG_Units/Optimus_GT540_Hard_Reset_Soft_Reset.htmlFollow the hard reset instructions.
A couple Android handsets (like the Galaxy S, apparently) will lose their carrier unlocking after a hard reset, but
from what the Internet says you should be fine, and it should stay unlocked (in case you're unsure).
I know I shall wish to get rid of ads and remove/freeze unwanted features (I don't use either Facebook or Twitter, for example). So I shall need to 'root' it. Many of the 'how to' pages I found by Googling seem to be rather old (as you would expect with a phone of this generation). The 2 main methods I found mentioned are z4root and Universal Androot. Is anyone able to advise on their current availability and suitability for this particular phone?
This one is still 1.6 Should rooting be done before or after upgrading to 2.1? Upgrading beyond the officially supported 2.1 is probably beyond my technical competence anyway, even though it seems I'd need 2.2 to access offline Google maps (thanks, for that information, Sol). And that was part of the rationale for getting a smartphone anyway! But the problem is that I'm virtually technically illiterate so just looking at the instructions for those custom ROMs is scary. After all, this is my first mobile phone of any description. What (besides Google maps) will I miss if I don't even upgrade from 1.6 to 2.1?
Finally, do I need a web connection on the phone itself to root and/or upgrade, or will they work if the phone is connected by USB to my intenet-connected laptop which does not have a wireless modem, but does have Bluetooth (which I've never used).
First,
read my thoughts on rooting my Intercept along with
this post from Android Central. The Intercept post won't be useful to you on the actual rooting process or much on what to do afterward, but there are some relevant questions and ideas to your situation. That said...

Most instructions will be from upgrading/rooting 1.6 (Donut), and most custom ROMs like the CM6 spin should be pre-rooted both for your horror and convenience. Given your relative neophyte status though, I might recommend instead (if it wasn't likely clear already) to stay stock and just deal with the ads and lack of offline Google Maps as offline Google Maps is mostly what you'll lose. That and WiFi hotspot/tethering. Also, having the useless and unwanted apps won't kill you, either. Remember, this was supposed to be a temporary out of country holiday phone with GPS and access to your e-mail. Don't spend more time on tweaking this thing than necessary unless you plan on
keeping it or just want to learn how to fiddle with this crap.
The easiest way to upgrade to the official 2.1 Eclair update is to just get it on the internet, which will just involve turning on the WiFi connection and connecting it to your network. It should almost immediately pester you about a firmware update. If it doesn't, just go to the dial screen while online and enter:
*#*#2432546#*#*
That's T9 for *#*#CHECKIN#*#* if you're curious. It should force a firmware and app upgrade notice to 2.1.
Before you leave, you should borrow a friend's SIM card and test the phone though. It'd stink if you got all the way to your destination with this thing and find it doesn't work.
Thank you in advance for your patience, especially as I have a sneaking feeling that for me even to buy a mobile phone for such a wimpy reason is being anti-Mustachian, so I have no business to be asking for help here in these matters.
No worries, and I'd hardly call it anti-Mustachian if you turn around and re-sell the thing after you get back or suddenly find that you might actually
use it as just a tiny handheld computer around the house to keep the main computer off or in sleep mode more often,
especially if you got a good deal on the thing. My Intercept doubles as an HTPC remote, a forum reader, weather updater, e-mail checker, instant messenger, and none of these functions requires anything beyond the WiFi access. You could even technically convert it into a
VoIP handset if you wanted. Just some thoughts.
Finally, have a quick list of the most useful apps outside of Google Maps that you should consider installing for this phone:
K9 Mail (excellent email client)
Dolphin Mini (light web browser with compression)
Android Lost (helps locate a lost/stolen phone)
Flashlight (just that... turns your phone into a cheap, terrible torch by turning the screen white and setting brightness to 100%)
They should all be ad free. Good luck, hope this helps!
