I have installed may of these AWESOME kits they all worked flawless, now I want to do a little but more.. If I have a wireless-wire kit, can I buy another ap and connect it to have 2 ap’s talk to the main ap ? ( of course copy information like shared secret password & ssid info.
OR Do i need to buy 3 60g ap’s and re configure all 3.
You will need to purchase the AP version.

The kits only have a level 3 license that only allow for them to be stations or an AP for a single station. The AP versions have a level 4 license.

Ahh, ok. This makes sense thank you 
Then i would buy 3 of the AP_60g_ap’s put one as main and the other’s as clients. Will they do 400m distance still ?
You can use the ones from the kit or non-AP versions (as stations) to connect to the AP version. No need to spend extra on those.
Confusing, but also trying to order the correct equipment Are you saying order one wireless wire kit and a non ap version ?
No, order one wAP 60G AP (this will be your Main AP in your attached pic.)
Order one Wireless Wire kits to reconfigure as your two clients. Or, in place of the Wireless Wire kit, you can order two wAP 60G. The wAP 60G is the same devices as is in the Wireless Wire kit, but just one. I include this for availability reasons.
2frogs,
The 3 pieces you suggested arrived today, took me 3 min to change the config and have them all talking ! Thank you for your help sir !! YOU ROCK !
