Hopefully this isn't too much of a necro (the thread is on page 2) but IMO anything over 5-7 years is long term enough that stocks are the way to go. That means broad market index funds. I would also have somewhere between 0 and 40% in an international index fund depending on exactly how much of a real 'merican you are. Then whatever you decide contribute regularly (ie. set up auto contributions), turn on auto-re-invest, and then ignore it.
I also think "emergency funds" are for retards. You are essentially paying the inflation tax on several thousand dollars for no reason. You should be able to absorb any immediate emergencies on credit that gives you a 1-2 month window to cover them interest free either just via your income or temporarily pausing your investment contributions. Sure have a few hundred in cash at your house but any "emergency" fund at a financial institution is dumb.
Anyway, I'm going to use the vanguard funds as they're what I'm familiar with for the tl;dr:
1 brain cell: 100% VTWAX
2 brain cells: 66%/33% split VTSAX / VTIAX
america brain cells / I trust warren buffet implicitly: 100% VTSAX
