with both NIC's attached to a Cisco 4510....
What is the purpose of connecting to NICs to one switch? Load balancing?
If you have the two NICs connect in a managed switch with different Vlan, your NIC teaming must be in fault tolerant (failover) mode instead of load balancing. The common practice of failover is each NIC port connects to a different switch so if one switch goes down, other will pick up.
why it's not showing 2 GB and using both NIC's?
Link speed is not a sum of speed. If the link speed on your interface is 1GB, it's the maximum of link speed aprx. 1GB substract network overhead regardless the number of NICs in a team. So if you team 4 nics together, the link speed is still 1GB. If you have it load balancing, you will still have it 1GB but you have more room for traffic load.

what kind of link aggregation you set up?
You should choose performance+redundancy with LACP
Then you should configure etherchannel also with lacp
example:
conf t
int gi0/1
desc first_nic
channel-group mode passive
int gi0/2
desc second_nic
channel-group mode passive
int po1
switchport mode access
switchport access vlan XX <- put correct vlan number here
end
you can see, that cisco side is configured with lacp passive, so broadcoms should be configured with lacp active
