Step #3
Download my model's initial factory firmware image
PW3
factory_PW3_5.7.4_initial
factory_PW3_5.7.4_md5
This one?
md5 validation file may be used to confirm that the download was complete and correct.
umm How?

This is not normally required, it is only here for troubleshooting Step #4 problems.
The Kindle will not try to install a corrupted or incomplete update_*.bin name format file.
They are checksumed and the checksum is cryptographically signed.
But it does no harm to check it anyway.
badgoodDeb's way will work, although eyeballing that long number is not fun.
Linux (and similar for Mac machines) with both files in the same directory:
Code:
> ls -1
update_PW3_5.7.4_initial.bin
update_PW3_5.7.4_initial.bin.md5
Use the '-c' (check) option to the md5sum utility and the name of the validation file:
Code:
> md5sum -c update_PW3_5.7.4_initial.bin.md5
update_PW3_5.7.4_initial.bin: OK
The question of how to do this on a Windows box has come up and the answer is somewhere here, in this thread.
Use the "Thread Search" tool in the blue bar above to search for it.

Step #5 is Step #5, after doing that activity, go to Step #6.

Step #7:
The Kindle has no memory of what was on it before, so pick one.
I recommend the most recent listed in the spoiler (because you can re-jailbreak that one).
There are newer firmwares than those listed, but they can not be jailbroken.

Step #8:
'Must use' means: "Must use" - I can think of no other translation.
Both the KUAL menu system and the MrPI package installer for the PW3 are: "Un-archive to top of visible USB storage" packages.
That is to say, they do not need an "installer" to "install" them.
Just be sure that your un-archive tool is set to create the directory structure stored in the archive.
Any of our add-ins that are packaged in a file with the: update_*.bin name format must be installed with MrPI.
Just like Amazon's they are model locked and cryptographically signed.
The only reason for MrPI is that Amazon got tired of sharing their on-board installer application and changed it to not accept our packages.

Afterward:
Margins: Depends on the type of book and the firmware version running.
There is a thread about that question, the best summary I can give is: Maybe, Sometimes.
Screensavers: Yes
CM by ixtab: Usually. Nested collections are no longer supported (say thanks Amazon).
This one is firmware version specific, stay with the version in the Step 7 list and the answer is: Yes
We also have another tool for creating collections, LibrarianSync.
It can build collections based on the directory structure under /documents and it can build collections based on the output of Calibre.

JBpatch (by ixtab): No

A quick check shows that 13,500 PW-3 devices have been jail broken here (plus probably the same number in Russia and twice that in China - Russia and China have their own Kindle sites).
And since you seem to be the "ask before you act" type of person, I would say no chance at all.
