For reading the Qur'an, I'd recommend the 'The Noble Qur'an' software from Islamasoft. Quraan.com has the online version of the same translation.
For Hadith (Prophetic traditions), once again, Islamasoft has something called, aptly enough, 'The Hadith Software'. If you wish to view them online, I would recommend you give the excellent USC MSA website a visit. Four of the six major Hadith collections are there - Bukhari, Muslim, Malik's Muwatta, and Abu Dawud. Before you actually browse the collections, read that page and the topics under 'the Science of Hadith' to give you the proper perspective on how Muslims use Hadith, and how they have been transmitted.
Enjoy your readings!
