How can I get rid of weird stuff going on? Please help!

Question

Please some one help. Or re-direct me to a web site that can help.
I installed 10.5.1 on my G4 Powerbook 1.67 Mhz from OS 10.3.9
The first thing that went wrong was that the Sound application got grayed out after the restart. The mute button in the Preferences was clicked but grayed out. So I installed again like before. So it worked.
So next I put one of my folders I kept always on the Desktop, where I had saved over the years pictures and things of interest, to have a fast access. I put this folder in to the Dock and tested it and the folder expanded and showed all the files in stack mode or grid. That is the last time I saw the Folder working in the Dock. Next the Icon showed a ? (question mark) that meant the original could not be accessed. Well even though I new the Folder name for sure and searched it, it just had disappeared.
So next I went to Starbucks since I don't have DSL and Downloaded the upgrade to 10.5.2 than I went home. And just for the **** of it checked for new upgrades on my Dial-Up connection to find 4 new upgrades.(Safari 3.1, Leopard Graphic, Time Machine and Airport and Security 2008_002) Since it takes hours to download with my dial up connection I just choose to Download the Time Machine and Airport Update of 10.2 MB. It downloaded and up came the window that the new software needs a restart. So I clicked restart up comes a window that says "Installing 1 item". I had changed my Desktop image earlier but when the "Installing 1 item" window came up it changed back to the back ground that you first see on your desktop after installation. The cloud burst in purple??/
In the "Install 1 item" window the status bar started moving for about 1 inch saying "Configuring Installation" and than stopped. And that was it. I waited for about 45 minutes and since nothing happened and I had no options I had to hold the start button down to shut down. Now after a deal like this I run always Utilities to repair the Permissions. That program is totally out of whack. It stops shortly after you click Repair Permissions and says something like "Repairing Permission Estimated time less than a minute". Well it takes about 10 minutes, than the status bar moves a bit and it says "Estimated time 39 minutes and than immediately counts down (like seconds) to 0 and says that the permissions are repaired. I also see and old blank disk entry that I had ejected earlier that still shows up in the left pane of the Utilities window.When I click on it the Utilities window moves from the First Aid tab to the next tab thats called Erase and ask me if I want to erase the DVD. But there is NO DVD in my drive.Now after Disk Utilitie repaired the Permission the following text appears in the window.
ACL found but not expected on "Applications/Utilities"
ACL found but not expected on "Application"
ACL found but not expected on "Library"
Sometimes there are a few more lines of text like this but this is just showing while I type this.
So do you have any idea? what's going on. Otherwise everything seems to work alright like CS 2, Mail, Safari, Word and all my other programs. I also had weeded out as good as I could the old left over files and apps from OS 9 (classic)
Any help would surely be great. Sincerely Volker and thanks for reading this long request.

There's a lot there, so I'll start with the parts I can answer quickly.
The "ACL found but not expected..." messages can be safely ignored, so says this article

(look below all the "SUID" examples)
I had changed my Desktop image earlier but when the "Installing 1 item" window came up it changed back to the back ground that you first see on your desktop after installation.
Leopard installs updates a bit differently. If it's simply an application that does not change system files, it installs them like before, without having to restart. If the update is to the system, then you must immediately "restart," It then goes to that stars and purple screen to perform the installation. Before, it would do the installation while you still had control of the Mac and would prompt you to restart when it finished the installation. This change probably make things more secure and reliable, because you aren't allowed to do other things on the Mac while system updates are being installed.
Please post back with the remaining point of concern.
