New 21.5" imac & old g5 - transferring iphoto & itunes without other junk

Question

I just rec'd a new 21.5" iMac. My old G5 holds all of my iTunes and 4000 photos in iPhoto
I ran the migration assistant to transfer iTunes and iPhoto libraries to the new 21.5
Instead of iTunes & iPhoto data transferring, my new 21.5 is unnecessarily loaded with all of the "junk" my daughter has loaded onto the old G5 over the years
There is NOTHING important to lose on my new 21.5, and I'd appreciate deleting all of the newly imported "junk" - all important data is still on my G5, so an "erase and install" would at least start me back at the beginning.
I inserted the Mac OS X Install DVD with the intention of running an "erase and install" but couldn't find the "Select a Destination" pane as my "Everything Mac" booklet instructed.
So, now I've unnecessarily reinstalled Mac OS X on my disk "Macintosh HD" and still have all of the junk, but none of the intended transferred data (my music & photos!)
*I couldn't determine which discussion area was appropriate for this post - if I should move it, please let me know - thank you!*

Now to figure out how to move only my 4000 photos in iPhoto and my iTunes library
The structure of the iTunes folders has changed from that used by your old computer. If you just copy everything as is from the old computer, you won't be using the new structure (iTunes Media). iTunes will still work though but if you are fanatical about preserving all the changes in Snow Leopard, you'll move things carefully to see where they should be placed. I actually went into the iTunes application on Snow Leopard when the libraries were empty and then acquired a sample song, book, movie, etc to see where they were loaded in the structure. iTunes doesn't show the folder name you are going to have until you feed it some content via iTunes app. Unfortunately I cannot describe the folder hierarchy since that machine has been returned to Apple but you could quickly do the same thing I did. Or perhaps someone here will post the iTunes folder hierarchy (including the Mobile Apps).
