Issues monitoring the 2602i Cisco AP with Zabbix.

Question

Hi!
My workplace just bought a lot of Cisco AP (2602i) and a WLC 2500 and I'm in deep trouble trying to monitor them with Zabbix, wich is the SW we use for our whole Network.
After a lot of time I got to monitor the CPU use (in %), traffic of each interface, the AP serial number and the AP software version.
I really need to monitor how many clients are connected (associated) to each radio and if the AP mode Flex Connect it is activated or not.
I would really appreciate some help with this, I'm out of ideas!
Thanks you soooo very much!
Some extra info regarding my APs:

Hey Saul,
I didn't really solve my problem.
I managed to monitor some items (connected clients, rogue aps, eth rx total, eth tx total, last reboot reason, lwapp image version, lwapp os version, mac address eth, ap name, power status, ssh enable, shown in the attachment) but those are just regular items and, to be able to monitor them, after each OID I had to write the AP's mac address in decimal format  (which I did using Macro's to make it automatic, taking it from another OID). 
Now at this point I have two issues:
First - using this template, which I applied one per AP host referring to the WLC IP address, makes my Zabbix Queue and Zabbix busy unreachable poller processes go up to the sky, which is no good at all and that's why I'm still working on how to fix this (maybe changing the way I monitor de APs at all).
Second - I still couldn't monitor important stuff regarding reach radio (for example), since all my APs have two radios and I find it interesting to monitor which channel are they at. The issue with this is (after a little internet research) that Zabbix allows me to use a Discovery Rule with only one variable field, in this case, the AP's mac address. It wouldn't allow me to double the Discovery Rule.
Let me be more explicit regarding this second issue with an example.
1.3.6.1.4.1.9.9.513.1.2.1.1.21 is the OID where I can find info regarding the radio channel.
208.199.137.14.211.112 is my AP's mac
0 or 1 indicates which radio I'm talking about (also dynamic as you see).
So to get that info it would be something like (and its response):
1.3.6.1.4.1.9.9.513.1.2.1.1.21.208.199.137.14.211.112.0 =  STRING: "This is a 802.11b/g interface, slot ID is 0"
1.3.6.1.4.1.9.9.513.1.2.1.1.21.208.199.137.14.211.112.1 =  STRING: "This is a 802.11a interface, slot ID is 1"
So as you see, I have to variable fields, the AP's mac and the radio index (0 or 1).
I would really love to monitor it with the help of a discovery rule, a double one which doesn't exist.
Of course you can do it manually, for each of your AP's radios and for each of your APs but, in my network scenario, we have more than two or three APs so it makes this impossible and poorly efficient. 
I'm sorry for not having the answers and I really hope this helps you.
Cheers!
