I would recommend
Bible Gateway
for many translations as well as linked cross-references and very good search functions. My preference is the New American Standard as I believe it comes closer to real translation rather than an interpretation than any other text. Even so, some interpretation is inevitable. If you want to really dig there are inter-linear texts online which give the original language with a literal English translation. You can take the original word and use a lexicon.
I would also recommend using google frequently. There are many sites online that discuss Bible passages.
