LTM setup question

HI I plan to use the F5 as gateway to servers. The LTM will be connected to the switch and what i plan to do is that the incoming traffic destined to the VIP address's will reach the switch and will be sent to a IPS device for inspection and will then be returned back to the switch on a VLAN 200 and i plan to create a port-channel to F5 and assign the port-channel to the same VLAN 200 and that way all incoming traffic will reach the LTM. In order for the LTM to reach the physical servers i plan to take 3-4 ports and create a port-channel and set it up as a trunk link to the switch in order to reach those server VLAN's.

I'm using LTM 2000s and i was wondering if there's a guideline on the number of ports to use per trunk. I mean i will have 2 LACP bundle. One for VLAN 200 to get the incoming traffic in to LTm adn the other is a Trunk link to reach all the Server VLAN's. should i have like 3 ports for the incoming port-channel in vlan 200 and rest of ports for the trunk to reach to servers ???

So talking about VLAN's so, i'll need the following VLAN's if i go this correct.

A) Vlan 200 to connect to switch on a port-channel to receive traffic from Internet ( this will be external vlan) B) The VLAN's that the servers are on -- I guess i need to create 4-5 nternal VLAN's and assign IP's to them and they'll be used as gateway for the servers. C) Management Vlan - This is to gain access to LTM D) HA VLAN - since i've two LTM, i guess i'll need a seperate VLAN to set up HA as well.

I'd appreciate if you can validate the vlan requiremnts above. A sample config will be appreciated as that'll give me a good idea.
