I have my stock neck pup and a little 59 in the bridge. Just had the both pots replaced and a zolan(?) cap installed. The guitar seems to sound shrill to me now. Is it the tone pot or the cap or both causing this? Should I just go back to a 250k tone pot and leave the volume at 300k? The tone taper is weird to now, its either off or full on. Its difficult to blend it.

Are those 300k linear pots?
With the tone knob full clockwise, the tone pot and the cap are not affecting the tone. A higher value volume pot will sound brighter, and it's possible that your old pot was 10-20% low. If the new pot is close to spec, it's likely that there's close to 100k difference between the two, which would be noticeable.
Did you also have the treble bypass cap put on the volume pot? That will also make it sound more shrill.

KoKo Tele I honestly don't know if the pots are linear. I'm guessing the volume is but the tone is not.
The difference in between the old tone pot and the new tone pot could be the difference. I haven't had a chance to speak with the tech yet. I will be calling him today to find out.
I don't think a treble bypass cap was installed either.
I do know that the wiring was upgrading for better shielding and maybe this has allowed more signal through and I'm just not used to it.

The shielding won't be the difference. If anything, shielding increases capacitance and take a little high end off the signal.
Take the control plate off and look at the markings on the pots. If it says 300A, it's an audio taper pot. If it says 300B, it's a linear taper pot.

Ok spoke with the tech and here's what I found out. I forgot that the Hwy 1's are a Grease Bucket control. The original tone pot measured 249.6k and the replacement tone pot measured 273.4k so not that much of a difference. So we figured it had to be the cap that was put in. I had him take the new tone pot out and go back to the old one. Made the guitar "warmer" with a better sweep in the tone pot.
The volume pot is a new 300k its Gibson pot but I can't see an A or B on it. I don't know if the new volume pot plays a part in this but the guitar overall seems louder. I had to drastically change the settings on my amp. I've spent over an hour adjusting the pickup heights to change that but I don't seem to be getting anywhere.
It also seems that the old tone pot is contributing to my guitar picking up radio frequencies as it did not do that with the 300k tone pot installed.
