I think I fixed my problem with high cpu usage of soffice.bin. I upgraded xubuntu early(before the .1 release), and have had a few nagging issues, with libreoffice being one of the more annoying problems. It was randomly using 50%+ of both cores on my machine. I've been looking off and on for a few weeks now, and ran across a post from couple years ago that had the same problem. He fixed it by disabling an extension he forgot he installed. I looked at mine, and found an extension I forgot I installed. Disabled that, and so far it's been behaving.
My last bad problem is random lag connecting to windows server shares. Sometimes it's fast, sometimes it takes a literal minute to connect. My boss has been having the same issue, so that indicates a general update as being the cause, and not the distribution upgrade. Just need to track it down. Once I get that fixed, I'll be able to upgrade the boss' computer at the .1 release.
