I have the inter Vlan Routing configured between three Vlans however I just cannot grasp the concept on how to route all the vlan traffic to access a wireless router.

As in the Linksys would be the gateway towards the internet?
- Connect the router and the switch an a subnet (either on the existing vlans, or a one),
- Set a default route on the switch towards the router's IP
- Set up static routes on the router for the subnets routed by the switch, with the switch as a gateway.
- Make sure NAT is working for all of them.

Example:

You have 3 subnets, routed by the switch:
192.168.1.0/24, 192.168.2.0/24, 192.168.3.0/24
Let's say the switch is .1 on all of them.

You build a new little vlan/subnet between switch and router:
192.168.10.0/30
.1 is the switch, .2 is the router.

Switch set up with a default route 0.0.0.0/0 nexthop 192.168.10.2.

Router set up with routes:
192.168.1.0/24 nexthop 192.168.10.1
192.168.2.0/24 nexthop 192.168.10.1
192.168.3.0/24 nexthop 192.168.10.1

Router has a default route somewhere over the WAN interface.

Make sure the router/firewall permits the source addresses, and does provide NAT translation for them.

If you want to go fancy, you can start running a routing protocol between switch and router, but for only 3 subnets static should do.

I wasn't aware Linksys-WRT300N could support more than one subnet?

Looks like it does. Page 26 in the userguide I found: "Setup tap - Advanced routing".

Advanced Routing under Setup Tab is grayed out on Cisco Packet Tracer 5.3.3.0019 using Linksys-WRT300N with firmware 0.93.3.

Honestly maybe I'm headed down the wrong path.

Bottom line I have a cable modem connected to Linksys and want to provide Internet connectivity to all the vlan subnets using a level 3 multi-layer Cisco 3560 switch.

Sorry, I expected we're dealing with real hardware here... :)
Not sure what Packet Tracer implements of the WRT300N functionality.

Well if it helps, I do have real  3560 and couple 3550 Cisco switches.  The real Linksys is actually a E4200.

Rather than trying to connect cable modem --> wireless router --> Cisco 3550  can I get by configuring cable modem connected to 3550 layer 3 switch and use the routing of switch to provide WAN to LAN ?

Most Layer3 switches, including the Cisco 3550 and 3560 series don't provide NAT, so you'll need a router.
Or, if the cable modem is not just a bridge, but a router, it might do as well.
Most Linksys routers do have static route functionality at least, so check the manual for the E4200.
