I have a Cisco 2600 with multiple inside VLANs. How would I limit the usage on a specific VLAN?

Hello Jason,
you can do it by applying a service policy inbound to physical interface f0/0
access-list 121 permit ip vlan-source mask any
class-map vlanx_traffic
match ip address 121
policy-map limit_vlan_x
class vlanx_traffic
police 5000
int f0/0
service-policy input vlanx_traffic
Hope to help

Are you unable to use a service-policy under your FastE subinterfaces?
What kind of usage limitation did you want to implement? i.e. To, from or both to/from the VLANs; shaping or policing?

There is currently a 4.5 megabyte pipe coming into the router. I would like to limit one VLAN so that it can only use up to 3 MBPS of that circuit.

Would need much more in detail for suggesting what you might do.
However, in general, you often have a lot of control over bandwidth utilization when upstream of the circuit (outbound), but much, much less when downstream of the circuit (inbound). It's often easy to police inbound, but this often doesn't really guarantee inbound bandwidth utilization (again this is downsteam, not the same thing as 1st hop inbound).
