I think the CIA and SDI are more important than the MP for initial military wonders; the MP is better as a third or fourth military wonder because by then you should be able to afford building a nuclear stockpile. I also think it's generally a good idea to maintain a 2:1 econ:mil ratio for wonders, but not until you've already bought your first five or six econ wonders. Generally, the first six economic wonders should be Stock Market, Social Security System, Internet, Great Temple, National Research Lab, and Great Monument, and should generally be bought in that order.
The Stock Market is generally better than the Social Security System for a first wonder because it's a lot cheaper, so you can shave several days off your savings time. The Social Security System also works by a percentage (and is about equal to a Bank in its effect on your tax income), so it works better when you have a higher base income and does less when you have a lower base income; when you get your first wonder, the Stock Market's fixed +$10 bonus is often worth more than the SSS's percentage bonus, and even when it's not worth as much, the difference is far too small to matter compared to the delay the SSS would introduce into your wonder purchase schedule (never delay, always get a wonder every 30 days, even if you have to settle for a less powerful one... the sooner you buy this month's wonder, the sooner you can buy the next month's, and the one for the month after that, and so on).
The Great Monument is a bit of an oddity because sometimes it's a +4 happiness (+$8) wonder, and sometimes it's a +5 happiness (+$10) wonder; if your people already approve of your government type, it's only a +4 happiness wonder, but if they disapprove, then the GM is a +5 happiness wonder. For a typical nation working on its fifth or sixth econ wonder, the NRL's +5% population bonus (which is equivalent to a +5% income bonus) will generally be worth less than a +5 happiness GM, but more than a +4 happiness GM. When it's time to buy your fifth wonder, if your people don't like your government type, get the GM and save the NRL for the next month, and if your people do like your government type, get the NRL and save the GM for the next month.
The Internet and the Great Temple are practically the same, so it doesn't matter which of the two you buy first, unless for RP reasons you want to set your religion to a type your people don't like, in which case the GT should be bought before the Internet.
The benefits of a DRA aren't worth nearly as much as the bonuses of the econ wonders I listed above, if you're a tech seller; the profit you make off that extra foreign aid slot and the +3% population bonus will almost certainly not match the profit you'd get off of the econ wonders I listed above. If you're a tech buyer or a sender or receiver of lots of development aid, however, the DRA may be worth getting before the NRL and GM, but that's assuming you'll actually make use of all six aid slots on an ongoing basis.
