The good news is that your current funds aren't astronomically high and are no load funds.
The bad new is you could have easily had better diversification for cheaper than what you've been doing for the past decade and a half.
If you have no desire what-so-ever to learn about investing, move it to Vanguard and dump it all in to VTHRX (Target Retirement 2030 mentioned above).
If you do want to have an understanding of why I would say to go ahead and move it to VTHRX, then start reading the book list on bogleheads.org (the books aren't expensive, but the knowledge inside is worth a fortune).
The short and dirty is: Vanguard's Target Retirement Funds invest in their own low cost index funds, Total Stock Market, Total Bond Market and Total International Stock. The objective is not to figure out who's going to be the "winner" or "loser" this moth/year etc. The objective is the BE THE MARKET. The market overall has a fair return. Take that return, without excessive risk and only pay minimal costs - you will beat the average mutual fund that has high expenses and load fees. Remember, the funds that shoot up suddenly tend to tumble back down just as abruptly. There are fund managers trying to find the next big thing that fail 90% of the time, what makes you think you'll pick the right one?
on edit:
the funds you are currently in have expense ratios of 0.68%-0.78%, Vanguard Target Retirement 2030 only costs 0.17% - you are currently paying over 4 times too much
