Sounds like you are definitely on the right track, but a few things that might help you get organized better:
You need to figure out an
investment policy statement and your actual
asset allocation so you know when to rebalance.
You'll also need to consider
tax efficiency of funds so you know what to put in which account. Like I hold a total market real estate fund, but only inside a tax sheltered account like an IRA, TSP or 401k/403b... because that type of fund (bonds as well) tends to have high turnover and produce lots of dividends - taxable events - so you want it doing that in an account that won't make you have to pay taxes on each little dividend.
I like what is called a couch potato or lazy portfolio. That means once I figured out my ISP, then what I wanted to hold as far as mutual funds and asset allocation and settled on 3 funds (plus cash) to make a total couch potato/lazy portfolio of 4 funds/categories (counting the cash category). I basically set it up, rebalanced everything between those 4 categories and set up automatic investing in the main one I wanted to grow, and pretty much forgot about the whole thing for 6 months/a year. I'd pull up everything then and check the balances, but wouldn't change anything unless it was out of wack by more than 5%. Which means mostly I don't do anything other than some basic math and typing about 20 minutes a year - that is the "lazy" part.
https://www.bogleheads.org/wiki/FidelityWord of note that you may already be aware of: they are in process of removing the "Spartan" name on their low cost index fund series to be just "Fidelity" index funds so some things might have a name difference in any Bogleheads stuff (or in general) that you come across when discussing Fidelity stuff. But check the tickers to confirm they're the same funds if possible.
I hold all my investments at Fido because I prefer their overall customer service and functionality (but Vanguard is the gold standard so that's why I linked to the Bogleheads for Fido users like us). I hold only low cost (used to be Spartan) index funds (per the Bogleheads link above).
So as an example, I hold three mutual funds, across 5+ accounts (taxable, 2 Roth IRAs, rollovers...) and use an
excel from SquawkFox (but is really easy to make your own) to figure out when to rebalance. I just figured out what I want my asset allocation to be, then figured out what lazy portfolio I wanted (and I'm doing a 3 fund portfolio + a percentage in cash, so I needed 4 categories total). I plug the numbers in about every 6 months to a year, and decide if anything is more than 5% out of bounds, I'll rebalance.
The funds I hold are:
Fidelity Total Market Index Fund - Premium Class (FSTVX)Used to be called Fidelity Spartan Total Market Index FundHold this in IRA, taxable, Roth IRA and rollover.
Fidelity U.S. Bond Index Fund - Premium Class (FSITX)Used to be called Fidelity Spartan U.S. Bond Index Fund Only in an IRA.
FidelityŽ Real Estate Index Fund - Premium Class (FSRVX) Used to be called Fidelity Spartan Real Estate Index Fund Only in an IRA.
And as far as the FUSVX fund... I agree with Jetblast that it is a very decent fund, but if you have the ability to get the FSTVX then that is slightly superior for the same expense ratio.
