Re: International equities allocation
I know some people may bash me when I say this but I would take the simple route or maybe add one more fund if you so desire (intl' small cap). The first set-up is well diversified but there is, in my opinion, a point of saturation. I am sure some people will note that the additional funds will lower the std dev of your portfolio but to what expense and to what possible sacrafice of returns is my concern. FYI - I like the Dodge & Cox International fund and I own it. Excellent active mgt shop.
Also, b/c of your age, I would be prepared to change your allocation over time. The 20% bond allocation may not be so bad right now but if the equity markets get cheap I would drop back and go long in a heartbeat.
