HIGH rst probably works because it tells RC.5 to be an output pin.  If you added something like

TRIS_C = %00000000	'all outputs

near the beginning of your program (after the PLP commands, say), rst=1 might work again.

The HIGH command produces seven lines of assembly because it assigns I/O direction (i.e., makes the pin an output).  It could get expensive if you have a large program.  By assigning your pins I/O direction at the start, you assign I/O direction once.  From then on, you should be able to use rst=1 which produces a single line of assembly.
