Various ways to get PDFs on to the iPad. The one drawback is you have to load them into individual apps. So if you have more than one PDF reading/annotating program you'll have to separately load each document into each program.

To use goodreader as an example, you can drag PDFs into the Goodreader file sharing area in iTunes (no need to sync, they appear instantly after dropping), transfer via Wifi, download form e-mail or the web browser, use the cloud sharing/transfer programs like dropbox.

For DRM, I don't believe any DRM PDFs can be read currently. But not 100% sure.

Pdfs can be annotated with the $6.99 (for now, supposed to go up to $9.99 at some point) App iAnnotate. Haven't used it myself, reviews I've read are mixed. But looks pretty robust from videos etc. Negative comments are bout it being non-intuitive, mixed impressions on how well it works with a capacitive stylus etc.
