Can I ask why you added it to the network rather than standalone?
I have three computers that are printing to/scanning from it and an existing network that's well-secured, so I saw no advantage of trying to run it standalone when I could just get it on the existing network.
Also does it look easy to set up as standalone?
Can't say I'm sure. The directions are thorough, though, so I assume unless something goes wrong it should be straightforward enough. If anything, I'd guess it'd be a little easier depending on how well secured your network is.
One last question, is it any good?
I've been a vocal fan of Canon inkjets since a while ago, as I said on account of the combination of good print quality and being thrifty with ink. The ink tanks are also relatively "inexpensive" since they don't have much electronics on them (and you can actually see the ink level visually, so you know they're not ripping you off when it says it's empty). Not as big a fan in general of Canon's scanners, but it's an all-in-one so you're probably not buying it for fine art scanning.
As for this specific one, as a printer I have been VERY happy thus far. It takes an unusually long time to warm up after being turned on, but once it gets going its quite fast and the photo print quality was actually good enough to surprise me--VERY smooth colors, even on medium-quality inkjet paper. Rivals my dad's 7-ink-tank lower-end pro photo printer, I'd say.
The network scanning works fine as well, and the quality is acceptable as far as I've tested it. I don't use the bundled software, but Canon's scanner driver is decent and their print drivers are very good in my opinion.
My only complaints are that it doesn't seem to have an auto-on or auto-off feature, but that's relatively minor if you usually leave it closed since you need to walk over physically to open the front to print anyway, and you can turn it off when you grab your prints. I assume this is because it's a network model. Other complaint is the lack of automatic two-sided printing, which my older Canon printer had. I haven't checked if it can be hacked to do direct printing on CDRs yet (many of Canon's printers have this capability, but it's disabled in the US-release firmware and they don't include the tray with US models).
