Basic computer knowledge
I think you could go directly to Windows XP as it will be a bit more up to date. What you need to do is never lose patience, get yourself started with a book to learn the basics and practise a lot.
Never be scared if the computer stops working as you can always reload everything on it. That will be the best way to learn, by find it problems and then finding a solution to them.

How many VLANs are supported by a Cisco 1921 router?
There are 2 ways that the 1921 can support vlans.
If you purchase a 4 or 8 port switch module (EHWIC-4ESG or EHWIC-D-8ESG) for the 1921, the switch module can support 16 vlans.
The other option is set up one of the routed ports with sub-interfaces (one sub-interface per vlan) and attach the port to a trunk port on a switch.
You can create up to 1200 sub-interfaces on the 1900 (although I doubt you'd need that many without maxing the performance specs of the router)
