I haven't read through your code, but this sounds to me like a basic 
misunderstanding of how the hardware works.

The T0IF will ALWAYS get set when T0 overflows. It is just that the T0IE 
flag doesn't let the T0IF flag set the interrupt that causes the code to go 
to the interrupt routine.

So when you are looking for the T1 interrupt, you have to check the T0IE 
flag first to see if that is set, and if not, you want to ignore the T0IF 
interrupt flag, and check for the T1IE and T1IF flags.
