That's right. Heimdall is not to be used in recovery, only in this
so-called "download mode". On the Galaxy S (i9000) you'd get there
pressing Vol Down + Home + Power.

You might, and you might not. I remember doing this in my Galaxy S and
CM7 had to repartition my 2.1 (or something similar). So, the check for
and old
partition scheme *may* still be there, but if it isn't, the install
script may cancel early (likely) or fail later (unlikely, but possible).

The page explains that a bit: what you will extract from that .tar will
contain a recovery image embedded. So heimdall will flash it for you and a
reboot will get you to this new recovery version.

No.

If you can go back to download mode you are usually safe. I think there
is an option to do a more verbose logging so you can see where things
have failed. You can then try to go back to recovery mode and use adb to
extract a log file from your /sdcard.
