No preparation. The image you copy with dd already contains a valid mbr
+ ext2 partition. So after the dd command, you should be able already to
mount the ext2 partition. If this does not work - something is already
odd - so make sure that mounting it already succeeds ! (Let's call it
step 0).

Yes

There should be exactly one partition to delete.

>>> 3. Resizefs operation

Yes

The first 3 steps are ok. If the 4. step does not succeed something
failed during re-partition and ext2 resize of the ext2 partition.
Effectively you should see on the ext2 partition the very same content
as after Step 0 (dd). The main goal of step 2-3 is to expand the ext2
partition over the whole USB stick - otherwise there is not enough place
for the VM image.
