does that mean I point the antenna south at 191 degrees to get channel 9?
Real channel 9 is a VHF-High channel. The "V" dipole kit that comes with the C2V should be aimed broadside to (perpendicular to) 191. The simple dipole for VHF-High doesn't have as much gain as the UHF loops but it is adequate for strong VHF signals. If the dipole doesn't have enough gain for channel 9 even with the preamp, it will be possible to add an inexpensive VHF antenna.

Is there a difference between a pre-amp and regular amp or is it all the same?
A preamp is mounted close to the antenna, and its power supply/power inserter is inside. The coax carries the DC power up to the preamp, and the signals travel down the same coax to the TV. A distribution amp is used inside to compensate for long coax runs after splitting if the passive splitter makes the signals too weak for more than one TV. Just use one TV for initial testing and then split.

C2V > FM trap > preamp > coax > grounding block > power inserter > TV

could using the pre-amp increase my chances at picking up that station I want
Yes, that is the purpose of a preamp.

You usually do not need a preamp AND a distribution amp; there is such a thing as too much amplification. Try just the preamp and a passive splitter first.
