It will help if you go and complete a full case study, as outlined here:
http://forum.mrmoneymustache.com/ask-a-mustachian/how-to-write-a-'case-study'-topic/This will help us focus on specific questions you have, recommendations, etc. For example, we don't know what type of accounts your stache is or how it is invested. We don't know if you plan to have children, when, if one of you intends to stay home. So on. Goals matter.
Looking over your budget, I wonder about things missing. Home maintenance costs? Restaurants, entertainment cost, clothing, cell phones, etc? Miscellaneous isn't a real category ;) Do you track your expenses real time, with a service like Mint, Personal Capital, or YNAB? This is a vital first step.
And then one that I like to point out to everyone who comes through with a case study: be sure you have advance directives in place, and insurance (life, disability, etc) as appropriate for your situation.
