If I understand the info correctly uhf stations will likely be reduced and moved to vhf correct?

The auction allows each broadcaster a number of choices, each one for a different amount of money.

The clearstream 4v is a poor quality vhf antenna so after switch over I am thinking a different antenna will need to be considered, am I looking at this correctly?

The CS4V is not a poor quality antenna but the "V" of the CS4V is a simple dipole with a gain of 0 dBd, or 2.1 dBi, which is the same as what the NM figure on your tvfool report uses. The dipole is useful for strong VHF signals and can be aimed in a different direction than the UHF section. What VHF channels do you want? WSYX is UHF.
At my location I use a 4-bay UHF antenna with a folded dipole for VHF-High.
What is so important about WSYX? You have a stronger ABC channel WEWS.
If WSYX is vital, you could have a friend stream it from his location with a Slingbox.
Looking at the coverage map for WSYX, you can see that there is no signal left at the receiving antenna:

what would you recommend for an overload resistance pre-amp?

The best one available now is the Antennas Direct Juice.
What you would need for WSYX is a separate high gain UHF antenna like a DB8e with both panels aimed at WSYX, a 91XG, or two 91XGs combined, a high gain low noise preamp, and a custom bandpass filter for real channel 48 from Tin Lee. The usual single channel bandpass filter might have too much insertion loss for channel 48. Maybe a custom filter that is highpass below 48 combined with a lowpass above 48 to block LTE would have less insertion loss. Channel 51 probably isn't strong enough to cause a problem to 48. The Juice preamp has an internal LTE filter, so all you would need is a simple highpass filter between the antenna and the input of the preamp.
As a simple test now you could use the high section of a UVSJ which would attenuate FM and WMFD, but it wouldn't attenuate 41 and 43. The custom highpass filter would be needed to do that. Talk to the Tin Lee engineer and email your tvfool report to him. No guarantee that this will work, but it is the best idea I have now.

The Juice preamp does have an LTE filter but does not have an FM filter; you can add one if needed.
