Heater Core replacement tips?

[79BIG10]

Well on the way to work today (even though the heater wasn't on) I noticed that sweet smell and saw a tiny drip on the passenger side starting to begin. I saw that the heater core is starting to leak so time to replace ASAP. I saw the articles here http://coloradok5.com/heatercore.shtml but was wondering if anyone else had more tips on this. I've already changed out the antifreeze and radiator cap (I'll replace the hoses while I'm there and the core is out) but need to find out if anything else I might want to change while I'm there.
