Upgrading Cisco 1142N lightweight wireless access point

I am looking for some guidance on updating my lightweight wireless access points, which are AIR-LAP1142N models.  I have 63 of them and they are all controlled by Cisco 5508 Wireless Controllers running version 8.  I also have Cisco Prime Infrastructure 3.1 if that matters.  Anyway, the access points all report that they are on Software version 7.4.100.60 and Boot image version 12.4.18.0.

I was able to download the latest software but the boot image tells me that I require additional entitlement to download it.  I am not sure what the difference is exactly so I was wondering if someone can enlighten me on:
1) What is the difference between the two and can I just install the software?
2) What is the best method of updating the 63 access points?  I don't see an easy way to do it in Prime.  I do have a tftp server.

I have an access point in my office to test with to be safe.

Installation of AP code is via the WLC. When you upgrade the WLC code it will automatically upgrade the AP code too.

Be careful though. The 1142 is only partially supported after 8.0 code. You can use them but WLC features added in 8.1 and newer won't be available.

I didn't realize that the controller handled the updating to the lwaps.  I did download and apply 8.0 to the controller and all access points upgraded themselves just fine.  It took a while but that's why there are "after hours" maintenance periods.   I guess I realized the value of lightweight managed access points.  Thanks for the tip on the 1142 compatibility.
