Typical setup in a multiple VLAN environment uses the default, VLAN 1 as the management VLAN.
You would use your management VLAN and it's associated subnet to address all network appliances. This VLAN is used for no other purposes (ie: client IP's etc).
You already have your gateway, the 2800 router, configured with a "management VLAN" IP adress (192.168.0.15) on the internal interface. From what you write, it looks like you have everything setup and working with regard to accessing the internet.
The simplest scenario would be to assign those two switches IP's in the same VLAN
Once you have your management VLAN and all appliances connected to it, communicating properly you can begin creating your new VLAN's.
Each VLAN will be a unique subnet and will have it's own gateway IP associated with it. You will then need to create routes from the new VLAN's to the management VLAN in order to provide them with external connectivity.
VLAN 2 = 192.168.2.0/24
VLAN 3 = 192.168.3.0/24
VLAN 4 = 192.168.4.0/24
We use .250 as our default gateway for every subnet here where I work so I used that in this example. You can set whatever standard you wish.
You'll also notice I made the VLAN tag match the subnet. It's a handy idea that makes things easier to remember. If I were you, before I did anything else, I'd change VLAN 1 to 192.168.1.0/24
