I think your strategy is well thought out. I don't think it is particularly risky considering you are now 35 and will be investing for the long term. According to John Hussman, two factors are important in achieving wealth (a) the number of years you are consistently saving and investing and (b) the proportion of funds allocated to higher returning investments such as stocks. You have a long investment horizon ahead of you; you intend to invest regularly and you intend to invest mainly in stocks, so you have a good plan.
I'd go for commodities. (I do.) Historically, commodities have delivered returns roughly equivalent to US equities, but with higher volatility and lower correlation. So including commodities should provide substantial diversification benefits.
If you think 20% to commodities is too much you could split your allocation 10% to commodities and 10% to property. Then you'ld have everything covered.
I agree with Jim207, post #3, you need 5,000 minimum to invest otherwise it just gets eaten up by fees so invest your initial 10,000 in two of your asset classes and then save up until you can invest another 5,000. And do it in blocks of 5,000, and not 1,500 monthly. When you start getting dividends you can add these to your investments.
