I recently came across two very helpful websites. The first, Documenta Catholica Omnia, is a huge compendium of every extant writing of all the church fathers, extending well into the Medieval period. All the originals are included (mostly Latin and Greek, but occasionally in Syriac or some other minor language), and any available translation into English or other modern languages, when not protected by copyright laws, is also provided. A phenomenal way to become more acquainted with the theological growth of the early Church, and to realize just how great our debt is to those fathers who gave their lives for the clarification and explication of the one, holy, and catholic faith (and by "catholic" I don't mean any of the popery that grew up later as a cankerous plague!). The second is an online, searchable version of Liddell and Scott's classic and hugely helpful Greek-English lexicon. Searching by Latin transliteration makes it easy to use with a standard keyboard. For instance, if you want the Greek word for "faith," you would just type in the Latin transliteration "pistis," and the corresponding word would pop up in Greek characters. Enjoy!
