Don't worry so much about consolidating your stuff because you both have things--over time, you WILL consolidate your stuff together, because you'll come to realize--hmm, do we REALLY need two of these items? The answer is usually no. Donate things that you haven't used recently--if you haven't needed it in the last year or so, you likely won't miss it. It's hard to overcome sentimentality, but sometimes it needs to be done.
Oh, and Craigslisting stuff can be a great way to make some quick cash
