In my opinion investment advice is best obtained over at the bogleheads forum. You can post all your details and they will give some great advice. Your income sounds solid, congrats. You can keep more of it by sending as much as you can to your tax-deferred accounts like your 403b. You also happen to qualify for a deductible IRA, some here don't because their income exceeds the cutoff. Your max for your 403b should be 18k this year. Does the place you work for match by any chance? I used to get a 403b but they didn't match and heck I never even maxed it out but I made a little less than you then.
Stocks and bonds, that's a good start. If you don't know much about investing yet there are a few good books out there, James Dahle, William Berstein, John Bogle and I'm sure a few other good ones that I can't recall. When you first start out try to stick with index funds (passive mutual funds). They are cheap to own, don't end up causing a lot of tax hits. Later when you learn more you can expand into individual stocks and more "exotic" things. You can buy shares of such an index fund that will hold a percentage of various markets, such as a broad hold of US stocks, broad international stocks, broad bonds etc... you can keep anything in your tax deferred accounts (403b, 401a, 401k, keogh) because you won't get a tax hit right now. But certain things tend to be better for taxable accounts (that would be a private brokerage account held at Fidelity/Vanguard/Charles Schwab). Oh and Schwab sucks donkey balls! I have been very happy with Vanguard and there is a good amount of nepotism towards Vanguard that you'll encounter on most of the great sites out there aimed at us amateur investors.
Congrats on getting rid of the car by the way!
