1) If I recall correctly, you can only have one active WDS AP in the broadcast domain. The Standby will not handle any traffic unless it decides that the Master has "gone away."
If you need a greater number to APs to be serviced, then the broadcast domain must be segmented, with a WDS serving AP in each broadcast domain (i.e., break up the wireless to different segments separated with a router, or VLAN ... one may be more appropriate than the other, depending on the other design elements of your LAN).
In addition to that, 60 concurrent WDS connections, is a hard limit. In additon to that, IMHO, that is "marketing optimism" and personally, I wouldn't trust a single AP to have to handle more than ~40 APs with average traffic and roaming activity.
Also keep in mind that 60 is given as the limit for a non-active (i.e., radios off) dedicated unit. If you need the AP to also service wireless traffic, then the number is halved.
2) As mentioned above, if you plan to service a high number of APs as the WDS service, then the radios should be off, implying that the only connection necessary is the Fast Ethernet.
3) WDS only comes into play with LEAP and EAP-FAST. WPA or WPA2 will not use (to the best of my recollection) WDS credential caching ... meaning that you would get no benefit to WDS using WPA1/2).
Q1: If the 120AP need to be in the wireless domain, I need to have 2 WDS master??
A1: Yes. And remember 2 things. (1) You'll need to segment the 120APs into 2 60 AP subnets because only 1 AP-based WDS can be active on a subnet at a time. (2) To support 60 APs, the WDS must be dedicated to running WDS. The easiest way to do this is to start the WDS and then turn the AP's radios off.
Q3:Meaning WPA/WPA2 is supported for the client authentication??
A3: Yes. There's been some confusion out there on this topic. Some of our competitors have been spreading lies on this front, but WPA/WPAv2 has always been supported for client authentication.
Q4: does the WDS/WLSE and APs need to be on the same IP subnet??
A4: No. If you're using AP-based WDS, the WDS and APs need to be on the same management subnet. The WLSE just needs to be IP reachable
Q5: can the WDS only be contacted by the APs via wired LAN??
