Ah. xterm have lots of knobs, but it's not always so easy to figure them 
all out.

The delete thing, for example, can work in several ways. If you press 
control and the left mouse button, you should get a menu where you can 
deselect "Delete is DEL". I suspect you have that selected right now.

As for keyboard behavior, you have several parts to it. One is that 
xterm can also "emulate" other keyboard than DEC ones. See that menu 
mentioned above again.
Second, the numeric keyboard on a VT100 can actually send different 
codes, depending on mode. The computer can send specific escape 
sequences to change the number keypad into and out of application mode. 
And depending on that, the keys send different stuff. If you press 
controler and the middle mouse button, you'll find another menu, where 
you can manually turn on and off application keypad, as well as 
application cursor keys.

The man-page for xterm is really long, but read it through once or 
twice, and you'll find all you need in there.

The things I mentioned in the menus are also available as command line 
switches, and also as X resources.
