Hi all, some questions
1.Do I need to put an ip on the ap manager interface?
2.does the ap manager interface go on the same subnet at the access points?
3.Im using 2 wlc's for redudancy, what special config do I need to do on them, do I need to tell each WLC what the other WLC is?
4.should I set the WLC addresses on the access points manually to avoid inter controller roaming?

1) Yes
2) Yes
3) They will participate in the same group
here are some good links:

4) that depends... some people prefer to assign static ips to the APs, it really depends on your preference and how many APs.
Currently, I use dhcp with the scope split between 2 dhcp servers with a long lease

Eric has some good docs there.
The management and ap-manager must be on the same subnet and of course must have an ip address. So you will need 4 ip addresses in that subnet if you have two WLC's and if you configure LAG. Cisco mentions not having more than 20 ap's on the same subnet as the ap-manager, so if you have more, You should create an AP subnet but have no more than 60 ap's on that subnet.
To avoid inter-controller roaming, make sure ap's are grouped together and is primary on one of the controllers. For example, if you have 6 floors 1-6, floors 1-3 should be put on wlc1 and 4-6 on wlc2. Don't try to mix and match on the same floor. I think they call it salt-n-pepper design.
Take a look at this doc also:
