First of all your card is very slow, you shouldn't use Mounts2SD (or other A2SD) with such a slow card. Second, something is wrong with your Davlik cache (that is what "updating apps" message means - rebuilding Dalvik). I assume you moved Dalvik to SD, so the problem is again in your SD card. Just buy a new one - Class 10. Also when using Mounts2SD don't move app data to SD, it will slow your phone.
Bought a new class 10 sd card. After all the work of getting a clean install of 4.3.1., after getting all the apps, and setting everything, on a reboot, the phone started to update apps and when it finished, it get an error about "theme managment" not working, or something like that. After that it reboots and start to update all the apps again. Back to 4.2.2, glad I got a backup...
BTW, I'm using mount2sd with only apps and dalvik cache on sd.
