I'm now positive something went terribly wrong in my install process as phone was just horribly unresponsive. I took my storage card out and did a hard reset. Ignored the phone for a few minutes and when I came back only Provisioning needed to be done.
After reboot I started setting up my screens etc. Much better setup this time around.
For some weird reason, I could not get Internet access and had to run carrier provisioning again, but that seemed to fix it.
With my particular screen setup (3 Lifestyle only, comprised mostly of shortcuts to a few programs and contacts - I don't do Twitter/Facebook/Media on my phone) I have right at 90MB free. With 23549 I was in the 40s. System seems responsive so far. Will report again after a couple of full work days.

Thanks formula.
