Ok to add several points:

For the dude running out of space, make sure you are syncing stuff to your IS not your phone's memory. I have no clue what it could be but after you flash a ROM go through each directory in File Explorer and find out where all the space is going. Make sure you sync attachments and pictures on the IS.

As far as the freezes, uncook Showcase Task Manager or use the cab Calk posted a few pages back. That will fix it fine. There is still the HTC Task Manager (it should be cooked in). For me the little icon doesn't show up but it's right under the clock and works just fine.

As far as the more stable ROM, they are both fine but if you're gonna use Manila use 23053 otherwise 23414 is fine. As far as we can determine something about 414 the top notification icons don't jive with Manila.
