In the event of a financial meltdown in the USA and the possibility of the dollar being devalued to $0 or close (fiat dollars?), what is the best thing to do with my funds, what should I buy, (I don't want to invest at my age) and where is the best place to put funds to insure some kind of monetary survival?

To provide a little more clarity, I have just a little cash (several $k) in credit union money market, close to $20k in a work 401k (money market-no MF), and owe around $30k on my house with around 10 years to go on a 15yr loan @ 5%. Also have a couple $k for emergency things. I'll also probably be forced to retire (with a pension) sometime this year.

I don't have much confidence in the market/mutual funds so I pulled it out into MM. I'm being told to buy gold/silver/platinum bullion (not ETF's) regardless what the price is now, because it will keep going up (possibly anywhere around 4k-10k T.O.). This could be the time to sit on some silver too, they say.

At this particular time in my universe, I'll be happy to keep/hide whatever I have before the big hands on the hill grab it. I don't know much about the market, and frankly I don't want to lose what I have accumulated trying to make more is an unstable environment. I'm just trying to find ways to balance out what I have in order to make it through a possible monetary collapse, and yes, it can happen according to many people smarter than I.
As I understand it, the feds moving $1T into the central bank is probably the last ditch effort for this recovery attempt and if that doesn't work the next step would be "fiat dollars" and the dreaded government annouced "bank holiday".

Also, how do you feel about keeping Treasury Bonds (the kind you get at your workplace through a payroll deduction that matures over time) at this time? Are they still good to hold on to or should I convert them to an IRA, etc??
