To read PDF and .epub E-Books on an iOS Device you can use Apple’s iBooks App.
1) Drop your PDF or .epub files into iTunes
2) Connect you iOS Device and choose to sync books
With iBooks you can also highlight in .epub documents. This doesn’t work with PDF documents.
To read and annotate (highlight and write on) PDF (as well as Word or PowerPoint) documents on your iPad I would recommend you to use an App named iAnnotate.

X) Buy and install iAnnotate
X) Once you have installed the application hit
