What share do you login to via AFP.

it cannot however be mounted - in fact the error message is"The operation cannot be completed because the original item for iMac.sparsebundle cannot be found"

You can't mount a sparsebundle over CIFS, only AFP. This may not be the problem here.

In addition it can't be seen when I go in via SSH either.

It will be there, you just don't know the path. It may be somewhere like /c/home/admin. If you look in the /etc/passwd file you will see the location of the home share for the "admin" user (If that's the share in which the sparsebundle is stored).

In addition, I'm noticing that when I enable Timemachine in frontview it still has the 0GB of Max 741GB Capacity showing, even after i change it an apply, hitting refresh takes it back to 0GB again.

You can try clearing the web browser cache (e.g. Safari > Empty Cache). Also I have some useful commands giving info regarding Time Machine on the ReadyNAS listed here: http://www.readynas.com/forum/viewtopic.php?f=18&t=42033&p=239030

The repquota command will tell you the quota for the ReadyNAS Time Machine user and conclusively tell you if it's set to what you want it. On one platform you need to use grep "text" for the code after the "|" separator on that line and on the other one you need to not use quotes.
