Just create a new breakpoint where you want it to stop next. You can do this 
while the program is still busy doing something. Once it stopped, you may 
inspect variables as already known. To restart it, just press the restart 
button.

No.

There is the possibility to set watchpoints. They work like breakpoints but 
are evaluated for every executed line of code. That means, if you are 
interested in a specific change of a variable (e.g. foo == "bar"), you can 
use this function. The variables of the frame the watchpoint fired are shown 
as usual.
