250 contacts is reasonable for a mobile device. 2000 would be a problem, especially on the Touch.

My PIM file has about 180 contacts and 200 Appointments, and this uses 2MB of ROM to store. With any more than twice this amount, you will find the device slows, and opening the Contacts application will take a long time.

With regard to the fact that nothing now synchronises, this suggests the ActiveSync log file has become totally confused.

Removing Activesync is not simply a question of uninstalling via the PC's control panel- as usualy with MS stuff, it leaves a large amount of residual data including the sync history on the PC. Once AS is uninstalled, it is necessary to use Windows File Explorer and locate the Program Files/Microsoft ActiveSync folder, then physically delete this folder. You should then go back to the Touch, select ActieSync, and then Menu/Options. There should be an entry for Windows PC, and if there have been some problems, possibly a Windows PC 2. Tap each of these headings in turn and select 'Delete' from the lower menu, to remove all vestiges of a Sync history.

Now reinstall ActiveSync 4.5 on the PC, and go through the process of creating a partnership again. This may only get back those items that originally synced, but it would be some progress!
