A: It will not help with shifting. It will only reduce drag a tiny bit on your drive train and look nice.

**Q: Are these wheels labeled for position, upper and lower like the oem wheels? also are they labeled for rotation direction?**
A: No, they are identical. Either wheel can go in either position and spin either direction.

**Q: Do these work with sram and/or shimano derailleurs?**
A: Yes.  Make sure you use the same number of teeth as the cogs on your current derailleur.
