Then, the next time I came out and turned it on, the radio wouldn't power up at all. Occasionally, when checking the SWR the ANT light would come on , but I never left it on for more than a second.
Is there anything else I can check/change to fix the SWR on my antenna? From what I've seen, many other people have used that kit successfully, so I doubt the problem is the equipment.
Since the CB won't power on, is it likely that I fried it with the high SWR readings?

Did you check for a blown fuse in the power source?

2. Check the center pin of the PL-259 antenna cable with a volt-ohm meter. The resistance should be infinity. Connect a 50 ohm dummy load to the radio's antenna input and key on. SWR should be near 1:1 or so.
3. If the radio's power cable contains an inline fuse check that the fuse is good or replace with a similar fuse for a test.
4. If all of the above are good to go then an radio internal fuse or protective component could be open. An inspection of the radio's circuit board could reveal a hot spot however not always.

SWR that you are describing makes me think the coax is not making a ground at the antenna mount
