I had many similar problems, so many, in fact, that I asked for (and got) my money back for the Lion purchase. Things are a little better if you do a clean install instead of an upgrade from Snow Leopard, and a little worse if you have been upgrading from before Snow Leopard to SL to Lion.
Yesterday my SSD died (writes failing in parts of the disk), and Lion seems more stable after restoring from Time Machine (which boggles my mind). It's all very weird and I've been calling it OS X Vista for the last four weeks or so. I hope 10.7.2 fixes the rest of the ugly bugs; most of the lost features and weird defaults can luckily be fixed on the commandline or with third party tools (but this, too, feels like Windows of old - "Sure, you can simply edit this 400-character registry key to get sane behavior!")
