Cisco 3550 Multi WAN and many vlans

Hello and happy Holidays all.

I have a Cisco 3550 switch I am setting up but having some issues with.
 
We have two different WAN connections from different providers.
We are using many internal vLANs.

Both fa 0/2 and 0/3 are drops from isp’s, I addressed vlan 1 with the assigned subnet from isp 1 and vlan 2 with subnet addressing from isp2. I want fa 0/2 to be assigned to the isp2 / vlan2, and fa 0/3 to use isp1/vlan1. Then assign other vlan’s to each of these trunked.  I enabled ip routing and input 2 routes, one to each of the isp provided gateways.
What else needs to be assigned or configured for this? After setting up the trunks I am having intermittent pings and remote access to the IOS is slow and hangs randomly.

ip subnet-zero
ip routing
spanning-tree mode pvst
spanning-tree extend system-id

interface FastEthernet0/2
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 2,6-31
 switchport mode trunk
 no ip address
!
interface FastEthernet0/3
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 1,3
 switchport mode trunk
 no ip address
!

I am also trying to setup ip helper address.
I have a dhcp server on vlan 6 to assign addresses into other vlans, through ip helper address I assume. Would I assign the helper address onto each desired vlan interface or eth interfaces and if so Is that all that needs to be done for helper address?

Thanks for any help!
