You can find 2.71 HEN and 2.80 HEN in my corruption-free downgrader
archives on this google page. You can also find them elsewhere, like
D_A's web site. The downgrader archives have HEN so that you can run
the downgrading homebrew, but you can also use the HEN to run things
like KeyCleaner. Read the readme that comes with the downgrader - you
want to follow the steps up through activating the HEN. Once the HEN
is activated, you can then run KeyCleaner.
Remember, HEN is meant for running homebrew on official firmware. 2.71
HEN is for official 2.71 Sony firmware, and 2.80 HEN is for 2.80
official firmware. I recommend those two since they use picture
exploits to activate. You COULD also use 3.03 HEN to do this, but it
requires the old GTA:LCS to work. If you have the proper GTA:LCS, feel
free to use 3.03 HEN instead.
> What are the steps I need to do in Key Cleaner to Unpatch my key 5?
Run KeyCleaner, tell it to analyze the keys, select analyze as a
TA-082/86, and if all the keys are fixed and key 5 is Chilly Willy
patched, you will be allowed to unpatch key 5. If the keys aren't
fixed, they need to be fixed before you are allowed to unpatch key 5.

I would do so just in case something goes wrong. The parts of the
idstorage in the NAND is specific to each PSP, so if you lose it
somehow, you are totally hosed unless you made a backup.

If you're on 1.50 and want to go back to official firmware, here's
what I'd do:
Decide which HEN you want to use - 2.71, 2.80, or 3.03 (3.03 requires
GTA:LCS). Install the official firmware for that specific HEN. If you
go with 2.71 HEN, 2.72 firmware will NOT work. Similarly, 2.81
firmware will NOT run 2.80 HEN. The firmware MUST match the HEN.
Activate the HEN using the instructions that come with it. For 3.03
HEN, that is loading a specific save file. For 2.71 or 2.80, that is
looking at a specific picture.
Run KeyCleaner. Analyze the keys. If they are all good with key 5
Chilly Willy patched, you will be asked if you wish to unpatch key 5.
If the keys aren't fixed, you should fix them. If you aren't sure, ask
here (be sure to write down what KC says about all the keys).
Once all the keys are fixed and key 5 unpatched, you can then run the
official firmware updater to the latest firmware.

Better to ask until you KNOW you're not doing something wrong that to
do something stupid and wind up with a bricked/unrecoverable PSP. Ask
whatever questions you feel are needed until you feel comfortable.
