There's some goofy stuff going on this thread.
First of all, although you didn't list every available fund and their expense ratio from your 401k, it looks super legit. Fidelity index funds with .04% isn't just "not bad", it's as good as you're going to get. So, looks like your fund options are very comparable to even investing in an IRA with Vanguard. Therefore, I suggest maxing out your 401k first. Especially with that income. You just need to change what funds you invest in within your 401k, you currently have some goofy ones.
Second, hopefully you meant switching from Roths to Traditional IRAs. IMS pointed out the IRA contribution limits ($5500 per person per year).
Third, you should be able to max out everything. If you can't, you should cut your expenses until you can. Seriously, if it wasn't for debt paydown, me and my fiance would be able to max my 401k + 2 IRAs with our combined income of 65k a year. With 105k a year you shouldn't have a problem putting away $29k or so pre-tax.
