Evangelical Outpost has good investment advice from Austin Pryor. It is worth a read.
I'm a young guy without much in the way of debt or long term savings. Right now my retirement money is sitting in a TSP account, that is the federal governments version of a 401k. Since I don't have that much to lose, I'm heavily invested in the riskier but higher yielding stock segments like small businesses and internationals. As I get older (and the interest rates improve) I'll shift more of my money to more secure investments like government securities and bonds.
My more immediate savings is going to be headed for an ING savings account. They have an excellent rate of return (for a savings account). This should get my house savings started.
