<human>: Condense the text into a few key points

I quit my job a couple of months ago and have roughly $150K combined between my 401(k) and Pension that I'd like to rollover to a Traditional IRA. Fidelity manages my former employer's 401(k) and Pension, though the funds available to choose from for the 401(k) were some custom funds with high prices that weren't from Fidelity and which I want to get out of. We had pretty limited options, but back before the company got cheap and pulled us out of our Fidelity funds, I typically invested in low cost index funds, primarily Mid-Cap and Small-Cap Growth Index funds offered by Fidelity. Back then it was easy because there were only one of each to choose from. Unfortunately when my former employer forced us out of Fidelity funds, I got pulled out of the Growth Index funds that were closed to new investors. So I know that I can't go back to what I used to have and am trying to determine best place to roll my money over to these days.

I've looked into Vanguard, as I've heard they have the lowest costs and after perusing their list of funds came up with these four that are of interest. However, I'd be interested to hear if there are others besides Vanguard or Fidelity I should look at that might have comparable low/no-fee, high performing growth funds such as these. 

1. Small-Cap Growth Index Admiral  (VMGMX)
1. Small-Cap Index Admiral Shares (VSMAX)
1. Mid-Cap Growth Index Admiral (VMGMX)
1. Mid-Cap Index Admiral Shares (VIMAX)

I also looked at Fidelity's site, but navigating their list of funds is a pretty horrible experience and I didn't really find anything close to what I was looking for there. 

Also, each company has their own terminology and while I understand that Admiral Shares are for $10K or more in investments (with Vanguard), I'm not clear on if there are other Share classes above that which I may be eligible for based on the amount I intend to roll over.
