A few initial points:
How long have you been in this situation? For a stated savings rate of 51%, you don't have a lot of assets. It's no shame to have recently seen the light, but without context it is also hard to judge just how complete and accurate your budget categories are.
Next, how long do you intend to stay in this situation? You mention shutting down your US checking account, but say you still have $10k stashed in the US. If you are thinking of this as lasting a handful of years, it may be useful to think about how you repatriate your money, too--and it is much harder to open a US account as a non-resident, than to maintain your old US account with a forwarding / local address.
Is your local country a high-tax jurisdiction? given that you make much more than the foreign earned income exemption, you would probably be using the foreign tax credit. So, if your local tax rate (net, not headline number) is higher than it is in the US, you will basically not pay anything. You do still need to file, though--and file all financial documents, like FBAR, not just the tax return. Looking at your take home vs. gross earnings, it sounds like this could be true.
Don't forget to look at the public pension as well as your company pension. This will affect your US social security payment--it can add to it, if you don't get enough credit in the local country to earn a pension there. Or, if you do get a foreign pension, it can actually take away from the US payment.
Regarding the employer's pension, is it a defined contribution plan? understand that very few outside of Canada and the UK are considered tax sheltered from the US standpoint. Instead, this would be viewed as a taxable account. Depending on the taxes you have paid on your salary, you may or may not be able to shelter this from US taxes.
In terms of what & where you want to invest: what are your future goals? If you want to return to the US, then by all means rack up dollars. If you are going elsewhere, the answer is different. I am setting up my stash for spending where I will be when I will spend it; to do otherwise risks ongoing currency risk. Of course, high returns could overcome this; so could extreme currency values in the meantime (e.g. the British Pound right now) But in general, set yourself up with the currency you are going to want to spend later.
Finally, looking at your non-US investment choices, it seems that you are aware of PFIC's, since you haven't listed any mutual funds? But you do mention real estate deals--understand rent as income is a qualifier for PFIC status.
