Half a year ago I used a Google Apps for Business account for pretty much the same things (minus Blogspot, domains, voice, plus address book and Hangouts).
Now I only have a non-apps account for Google Scholar. Besides that I have moved everything off Google. The most painful thing was losing all paid Android apps, but since I planned on moving back to iOS again I took the loss. All the other stuff was not hard: I switched to Fastmail for e-mail, who have a nice migration tool, calendars and contacts are on iCloud (since my wife uses iCloud as well), files are on Dropbox.
If possible, I would like to switch away from Dropbox to something that is end-to-end encrypted. We used Bittorrent Sync for quite some time, but I had serious problems in the last few versions (basically, it corrupted its own metadata and re-added all shares from scratch). Syncthing is not really an option (too hard to share with family/colleagues).
Regarding moving from Dropbox to something encrypted, you might look into SpiderOak - I've not used them, but they've been around for quite a while and "encrypted zero-knowledge" is basically their selling point.
I don't believe they have a free tier, so I suspect they have a sustainable revenue model - basically everyone's on their equivalent of Dropbox Pro, with no free account leeches eating up their marketing budget.
