You just have to enable intervlan routing and create appropriate NAT statements for getting connected.

As you already have configured inter-vlan routing on the router for all the vlans, you have enable "NAT Inside " on the sub-interfaces for inside LAN and " NAT Outside " for natting all of the subnets to the internet facing interface.
You have use ACL's to define the interesting traffic to go outside and use the "NAT inside " statement " only on the sub-interfaces that you want to acess the internet.
Please find the doc below for configuring NAT on the router.
