Yes, please break down your numbers further.
Sell the PITA rental. Sell one car.
I'm seeing that you have $70,000 in savings, and your wife has $6,000 in savings: $76,000 cash.
Keep $6,000 as your emergency fund.
Put $22,000 into ROTH IRAs by maxing out one for you and one for your wife for 2 years: $5,500/yr for you, $5,500/yr for wife.
Put $35,000 into her 403b by maxing it out for 2 years: $17,500/yr.
Sounds like you're self-employed. Put ~$26,000 into a SEP IRA for yourself two years: ~$13,000/yr... but I'd get advice from a tax professional, so you don't over or under contribute.
And, that's all $76,000.
http://www.irs.gov/Retirement-Plans/Retirement-Plans-for-Self-Employed-PeopleSounds like you also want investment advice. You can't go wrong with Vanguard. Maybe start with their Target Retirement Fund 2040 which is 63% U.S. stocks (VTSMX), 27% international stocks, 8% U.S. bonds, 2% international bonds. It'll automatically re-balance over the years to put you more and more into bonds as you get closer to 2040 (retirement!).
And, in the meantime, some educational reading:
