After installing 10.7.2 from scratch, permission errors remain

Question

Hey, this is a summery of what have happened:
1. upgraded to Lion from SL (via AppStore)
2. have played with 'get info' > 'apply to all enclosed items'  :/
3. things have gone messy, slow, permission errors. example:
(Warning: SUID file “System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAg ent” has been modified and will not be repaired.)
4. booted from DVD of Lion dmg.
then, formatted and performed a clean install.
(backed up to a new disk image with CCC, just in case)
5. Notice that I did not copy anything or downloaded/installed a single file/application yet.
after the so called 'clean' install, I've ran the disk utility to verify permissions again (both from DVD and from cmd+R - recovery partition).
still I get the warning about ARDAgent, still verifying and repairing permission takes 2-3 minutes. with only the OS X installed on HDD.
6. Got this advice from several boards:
Open Terminal as an admin user.
type in the following:
sudo chmod -RN ~
you will have to authenticate with a non-blank password.
then follow the steps of resetting the ACLs.
I have done this, and got: Failed to clear ACL on file ubiquity.socket: Invalid argument
Then, booted from DVD, in terminal typed: 'resetpassword' and chose the HDD and "user" and clicked on 'reset password and ACLs'.
restarted, Spotlight did index againg.
7. still permission errors, so I didn't copy anything back yet, waiting for help to get the right way or restoring to default/formatting again.
My questions are:
1. Did I do everything right? Is it possible to perform a clean install from the DVD that I made?
2. If so, shouldn't it cancel all the ACLs problems and reset them to the default?
3. Is there a way to make a real 100% clean install of 10.7.2, with erasing even the recovery partition (if it has to do with ACLs)?
4. if and when this will be solved, I will need to copy back my files and folders from external FW800 WesternDigital,
will I need to reset their permissions too somehow? It could cause more problems with the ACLs.
thank you very much.

baltwo,
I have a lion clone. so I guess there is no reason to install lion upon it's own clone.
anyways, how is it possible that after the complete format, the ACL problem remains.
what about removing the recovery partition.
the reason I want it to be done is to get rid of the problems I had with the new installation, tham I'm afraid will not be fixed otherwise: crashing apple applications (safari quitted unexpectedly), slow performance, computer freezes, GUI lags (copying 138 items to another folder stucks and I have to relounch finder) and other animation bugs at almost everywhere on the system.
restoring lion clone and turning on the time machine sounds like the last option right now...
and I'll be happy to hear opinions about what to do with the backed up data on the external hdd permissions.
