Not that I know of. You can load 16-bit registers from a fixed address, but
as far as I know, you can't do it from a register pointer address. But I
could be wrong (Heck, I only got this calculator 3 days ago, and I've never
owned a TI calculator before).

Yes. HL is the address of Label, and (HL) is the byte at the address in HL
(i.e. 3)
