I work in the mutual fund industry and am curious to know what you mean by "eaten up by fees." Give me some numbers to work with here. Also, I wouldn't look at the ER match as a protection against inflation. Inflation is essentially built into the returns of the funds, so that is your protection - not sitting in cash.
I'll probably get banned for this, but I would keep your 401k contribs going for now. Assess paying off the bad debts (what do you mean by that). Then work on saving for your Real Estate ventures. If this seems like it is going to take too long, then start trimming down your bad debt payoffs then your 401k last. Your 401k is going to be your back stop, and your just-incase-this-real-estate-venture-doesnt-payoff retirement. Most of the time your 401k money is protected from creditors.
I know BP makes REI look sexy and people are really making good money, but if you've got responsibilities, I wouldn't stop getting the free money from your ER.
And ffs if you have any decent investment options in your 401k, don't go with an Index fund.
