MAC OSX Tiger 10.4.3

I have been away from the MACOS approx 6 years now. And here it is, my first day with the Apple Tiger OS and it is beautiful. However, below is a list of probs I have so far. Any advice is greatly appreciated!
-cannot toggle to a docked finder window, you HAVE to click on it to open
-cannot rename files/folders within dialog window of an application
-i drag and drop a file 2 folders in from that directory (in column view), and the last two columns go blank! why?
-problem with burning a DVD with Apple OSX - doesnt tell you how much over you are on the DVD
-why do you have to hit apple+delete to delete a file? why not just 1 button delete key?
-No cut and paste option for files (takes longer to move files).
-Browsing for files from Safari to upload to a website is not intuitive. The folder structure is weird.
-Apple+tab to change between apps only switches to that app - not directly to the doc that is open with that app (text edit, safari and prolly more).
-Applications stay open even after you close the main window - Safari for example. The app is still hogging ram. Why?
-Cannot toggle between windows by Apple+tab. Example: 2 word docs open.
-There is no refresh option for Finder windows.
-Finder windows do not have a memory of overall size or column sizes?
-Do we have to type a password to install any application? Really great if it was an option and not a have to.
-The 2 delete keys do not have the same functionality. Why is this?

*Im not sayin that WIN XP is any better, and I have yet to try LINUX. The problem is that several of my friends have bragged about how much better the MAC OS is. So far, I greatly disagree.
