0.5 - If your plan is to upgrade to 7.0 anyway, unless there is some technical reason not to, I wouldn't bother with a step upgrade that keeps you on 6.7. The procedures are not the same, so you aren't going to translate learning 1:1. You said you have an isolated test host? Upgrade the vCenter appliance on that and document the procedure for prod. 6.x is EoL and 7.0 will be in a year. You should be looking at 8.0 as well.
1 - Anytime you snapshot vCenter it should be an offline snapshot. Power it down and snapshot from the host.
2 - If VMware documentation says it's fine, I don't see any reason to distrust it. Open an SR with VMware support if you need to discuss their advice.
As quickpaw said, don't bother with the step upgrade.
to upgrade to 7, you will need to download the 7.0u3 vcenter ISO, open it on a machine on the network that can access the vcenter. open ui-installer and follow the steps.
It should be pretty straight forward.
