You guys are a wealth of knowledge.
Here's my current 401k's distribution but I can change it at will to one of the Vanguard target funds or a reasonable combo from what they offer.

Can't tell if this is a good mix or if I am not doing as well as I could.
Way too complicated. I like that you have access to Vanguard large cap and bond funds. Some of those others might fill in the gaps, others are redundant, and you could work on getting the right allocations (assuming you don't just jump into a target fund).
Do you have access to Vanguard's extended market (read: small + mid cap) or international funds? If not, look into the other funds you have, which ones are index and low expense (hopefully), and consolidate your holdings.
If you were to mimic a target fund, and assuming it's far off into the future, you would have something like 54% domestic stock, 36% international, and 10% bonds. That 54% domestic would be split something like 40% large cap (S&P 500, or the institutional fund) and 14% small/mid. So if you could build something like that with low cost funds that might be available to you, then you would have an approximation of the 2055 target fund. (You might ask why not hold the target fund. If you like this allocation, then why not, indeed.)
You would also be free to deviate and build your own ratios. Vanguard is heavier on international than other target fund providers, for example. I believe Fidelity is closer to 30% of stock holdings being international instead of Vanguard's 40% (with 40% of 90% being the 36% that you see above).
