I now sync certain info to my icloud account. One of those things is my bookmarks. 2 weeks ago my PC hard drive died on me. after reloading my drive, I reinstalled safari on my pc and synced it with my icloud account. All my bookmarks were returned to my PC. The same would work for your ipad once you start syncing to icloud.
Could you sync your PC to icloud and then sync to ipad from icloud?
