The mail accounts are easy to move.... on the old PC, go to Tools / Accounts, and then export each of them to a file, then on the new one, do a Tools / Accounts, then import them.
To move your messages, right click on your inbox to find the location of your message store. Use explorer to browse there, and copy the files in that directory to a CD or something. Then on the new computer, go to file / import / messages.
If you want to grab your address book, on the old comp, go to Tools / Address Book. Select the contacts you want, and export to a .WAB file. Then on the new one, you can do a File / Import / Address Book.
Piece of cake.
