Does this mean I'm going to loose all my data?

No.
At least, you shouldn't, and doing the --create won't make anything
worse.

So do the --create with the 'missing', and don't add any spares.
Do a 'fsck' or whatever to check that everything is OK.

If it isn't, we'll have to look again at exactly what happened and
figure out which disks we should have created into the array.

mdadm: invalid number of raid devices: 28

Sorry.  Add
   -e 1

I'm using mdadm 2.0 now --- should I try 2.0-devel-3 ?

No.  -devel-3 should not be used anymore.
