Does the iPad not read pdfs natively as the iPod Touch does? Some pdfs convert gracefully into epub files, but some do not. If they don't, I'd look into a program like Drop Box or Drop Case to get the pdfs from your computer into your iPad. Assuming that the iPad can read pdfs.
The Ipad reads PDFs fine. Getting them into the iPad/pod/touch requires having them stored on line (Evernote/Mobile Me), in an ebook format, as a jpeg in iPhoto, in an email stored (gmail)

Work related single views are east to view/store in email
Work related multi view are easier to store in Evernote
text based ebook PDFs are easier to convert in Stanza to .epub and store in iTunes as iBook
Comic books are easier to get/convert to jpeg and store in iPhoto as album. Then sycn via iTunes for reading (or purchase with and app like Marvel)
Converting to PDFs can be done with many apps.
There is no one perfect solution to PDF storeage/viewing. It all depends on the type of PDF and how many times you need acess to it.
