Assuming you have a few grand in savings now to cover daily issues that pop up (you'd be amazed how many people do not)... then,
1. make sure you have life insurance to take care of your family in case you dont come home tomorrow or 10 years from now - enough to pay off house, send your wife to school if needed, help your kids with school, and provide a nice buffer fund to help them with other issues that will come up in normal life
2. pay down any consumer debt
3. build up a 6 month cash reserve, keep this pretty liquid, at least a couple months worth in a money market you can write a check from tomorrow if needed, the rest in a low risk fund if you want
4. max out any employer matched options like matched 401k, it's free money, dont leave it on the table
5. save as much as you can and find long term investment that fits your personality - this is where you can get personalized but unless you really have an interest in learning about markets and being very hands on (which most people will underperform if they chose to do and are being honest about it), you can find some solid index funds as a no-brainer way to start and read up on other funds if you like... find a reputable planner/mentor, despite what many do-it-yourself gurus proclaim, a good planner can help you from making stupid decisions, but get someone trusted by other people who are doing well financially dont just pick someone off the internet or phone book
* Alternatively, skip #5 until your house is paid off by just shoving every spare dollar at your mortgage. If you want to be a bit more hands on and are not attracted to playing markets, I'd also encourage you to look at long term real estate investing (not the flipping crap like you see on TV), as even seemingly unexciting options can really add up over time and you're developing not only equitable worth but also a steady source of passive income.
