My advice is to not view the Bible as Testaments or sections. View it as one big thing. As far as order is concerned, I'd treat it like this:
Genesis a mythology about the beginning of time, a worldwide disaster, and the founding of a nation [think Romulus and Remus when reading about Abraham]
Exodus an escape story; the true believers of a deity are held captive by a nation and a man who don't respect the god of the slaves; therefore, the god of that nation shows his power by destroying the former slave-masters and rescuing his believers...pretty riveting
Leviticus not as literary; think of it as a rulebook given to those that god saved. basically, "I saved you from a life of slavery; now you owe me. Do this and don't do that, etc."
Numbers retells some of the Exodus story, while documenting the time Israel spent wandering in the wilderness for disobeying god already.
Deuteronomy Moses' pep talk to the Israelites before they're finally allowed in to the land that god promised them; basically reminding them of what they've been through, encouraging them to be faithful to god, and energizing them for the coming task.
Joshua continues the story, as Joshua (not Moses) takes Israel into their Promised Land. Cool stories abound, especially one about walls of a city toppling down.
Judges a book that reminds me of Seutonius' 12 Caesars, in a way...basically the judges were the men/women that god chose to govern over his people during the time of their first years in their new land. there are good ones and there are bad ones, but most of them are pretty entertaining
Skip Ruth for now.
I/II Samuel tells the story of the last judge, Samuel, and the beginning of the kings of Israel. Starts with Saul, who was a great warrior but not so holy of a man and finishes with David, who was pretty much the Odysseus/Achilles/Aeneus of Jewish culture.
I/II Kings tells the story from David to Jehoiachin, the 400 year dynasty of kings in Israel. Mostly not so good kings, and Israel gets conquered by another nation, supposedly because they fell away from god again.
Skip ahead to Isaiah, Jeremiah, and Ezekiel and read those. Then go ahead and go to Hosea and read down through Malachi. Now, you have a basic chronological account of the history of Israel. Now, let's read some poetry.
Read Psalms (a huge list of poems and songs), Proverbs (a sort of Benjamin Franklin almanac of wise sayings), and Job (a sad story about how god allows those who love him to be tested, seemingly as some part of a cosmic game). Then read Song of Songs, Ruth, Lamentations, Ecclesiastes, and Esther. Next, read Daniel, Ezra, and Nehemiah. (Warning: Daniel is crazy). I'd skip the Chronicles. This is the order of the Tanakh, in case you were wondering. I think it gives the best order to read the 'Old Testament'.
Now, for the 'New Testament'. I would read Luke and then Acts (even though they're probably not by the same author, as once thought, they chronologically fit pretty well). After Acts, avoid the New Testament order and read Paul's epistles in the order he actually wrote them, rather than by size (how they're ordered now).
- I Thessalonians
- Galatians
- II Thessalonians
- I Corinthians
- Romans
- II Corinthians
- Philippians
- Colossians
- Philemon
- Ephesians
- I Timothy
- Titus
- II Timothy
Then, go ahead and read Hebrews through Jude. Give yourself a break. Refocus. Then give Revelations a go. After all that, if you want to read the other gospels, go ahead and do so.
