If the other comp is running windows,the easiest way would be copy that stuff to CD unless you have Gigs of stuff to move.You could setup samba but if you're not planning on keeping the two comps connected all the time,it wouldnt be worth it unless you want to try it as an exercise in Linux/windows networking

.
The actual importing is just clicking Bookmarks>Manage Bookmarks>Tools>Import and browsing to the directory where they're kept.
