For the first, the median stay is about 8 days (average gets drawn out by a low number of cases in hospital for months). This is down about a day from Alpha, mainly due to better triage and treatment options out of hospital. So we now send people home with dexamethasone and anti-coagulents, whereas in Alpha we may have at least started that treatment in hospital. So we get a big group staying in for a few nights, another group staying in for about 12 - 20 days (these are the cases that may end up in ICU) and finally some long term cases.

I haven't seen a recent breakdown for "admitted for COVID" and "admitted for something else but found to be COVID", but if I had to guess, the latter group is in the 30 to 40% area. It's complicated because if someone is experiencing dizzy spells and mild breathing problems, then the COVID diagnosis suddenly explains a lot, but that may not have been why they ended up in hospital - they may have taken a fall down some stairs and ended up as a 999 case. So separating this all out is problematic and unhelpful.
