Problems with migration on a new install

Question

I turned on my new 27" iMac, and when it asked if I wanted to import info, I was not ready because I did not have the right cable to connect my Time Machine External B/U, so I passed, and created a Bootcamp partition.
I installed Windows XP just fine, and then installed Parallels on the main admin account, and made sure it worked. then tried to import my prior user account by connecting both computers with an ethernet cable, and turned on file sharing. I had problems with lots of spinning beach ball of death on the old mac, so I figured moving to the new machine would get rid of it.
So I used Migration assistant to import from my current computer connected with Cat 5 cable, and it got 99% of the way through, then hung, like it could not gather the final info from the old computer to finish the migration, so I forced quit Migration on both computers, since there is no other way to exit w/o a successful install.
The account was there, though when I log in as that user, I see lots of folders I don't have permission to access like my documents and downloads.
So I go back to the old computer, and do an updated time machine back-up, then connect that external HD to the new iMac and do a 2nd import to a fresh user. All goes well, and I am able to log in, however, my new install of Parallels does not show up on the desktop, rather my old Parallels shows up with its different name. And I am getting spinning beach balls for 10-20 seconds in Safari, which I don't like, as something from the old computer must be corrupt to be doing this like a preference file or ?.
I have had a Mac since the early 1990's, and always only had one account that I used to run the computer, never creating a "User" account to run day to day, and I am not fully understanding the relationships between admin & user.
So my questions are;
1. what is the best way to take my documents, movies, photos, music and such from the 2nd migration, and transfer to a freshly created user account that would have no corrupted preferences causing the spinning problems. Do I put them in the shared folder, then access them from the new account, and transfer them that way, or does the admin do it?
2. What do I do about the applications that were imported, can the main admin move them and possibly the above documents to the main applications folder?
3. What about fonts and such, should they be put in the main library, or a user library?
4. Where can I find info on the allowable actions & limits of admin and users? what they can & can't do.
5. On my admin desktop, I can see my HD, Bootcamp partition, and Parallels shortcut. It is not visible on my test account, or another user account I created for #1 above. How can I give that user access?
6. How can I access the new Parallels install that shows up on the admin hd, instead of the old imported one in my user account?
7. How can I access the 2 external HD's that show up in admin and not users?
8. Can I safely delete the user that was created from my first unsuccessful migration that I had to force quit and has permission issues?
Thanks for your help, really appreciate getting up to speed on users...

No offense, though none of your replies are of any help. I am not migrating from a PPC to Intel, I don't need to reinstall, I am not a new user migrating for the first time, and I am not having any font problems.
Let me try again.
If I have a problem with an imported user account like it hangs doing certain things, how do I move all the data to a new user on the same PC, just drag all the documents, library, and similar folders to the shared folder, or the user folder?
Users/Shared
Users/User
Any help is greatly appreciated.
