Just to clarify. Are you also suggesting that I max out a 401k after I max the Roth out? I guess I have never thought about having 2 retirement accounts for myself, but it is a thought... I was thinking option 3 of having a taxable investment account might be my decision after funding my Roth. Income limitations shouldn't be a problem, my wife and I make ~$95,000 combined, and I think the limitations for a couple is ~$156,000 if my memory serves me correctly.
Just don't think of it as before and after, think of it in terms of priority. You're going to create a budget based on your income and expenses, at which point you'll have this bucket of money
(tm- Ray Lucia) called "retirement savings". As you figuratively pour money into retirement accounts, your particular priority is to the Roth IRA. If your bucket still has money left in it after filling up the Roth, start pouring it into the 401k, and so on until you've reached the limit your budget will allow. The literal pouring of money into these buckets may be concurrent.
If your overall finances between you and your wife are combined, you may also want to consider her retirement account options as well. Generally this involves putting 1st priority to contributing in her plan to the maximum match amount. (Then Roth IRA, then back to 401k, then taxable.) Each of you can (and probably should) have a Roth IRA.
As for multiple retirement accounts, although they have the same overall objective (growth for retirement) they have different advantages (contribution limits, tax-deferred growth/withdrawls, etc) so you should combine them to suit your needs. As a result of my own life's ups and downs over the years, I have accumulated funds in 3 retirement accounts: 401k, Roth IRA, & a Traditional IRA. As the year-end approaches and I get a better picture of my tax liability, I may be converting all or part of an IRA which might bring that down to 2.
