UPDATE
*******************************
I installed Blackberry Master Control Program. Worked like a charm. I have all of the required core applications, restored my third-party apps, Address Book, etc. It was like a wipe and reinstall without too much hassle. Some of the apps I had to re-register, in a sense; e.g. resubmit login info to GMail & Shazam, BBM reappeared in the uninstalled list because an update since my last install was available, reinstall of Opera Mini. But I now have the functionality that I want.
If you are having problems with loading apps I would recommend this highly to anyone
