Do I need to worry about doing any extra steps to cleaning the fermenter and keg when done with this beer? I normally do PBW with hot water then spray with star san after rinsing.

Oops sorry, some of those instructions I gave below were for buckets, you have a glass carboy, I've edited the post appropriately.
Use a carboy brush to clean/scrub the inside well, making sure to touch all surfaces. Glass is smooth and not permeable unlike plastic.
The sunbath won't apply as glass may filter most UV out, so I'd bleach bomb it after thorough cleaning. Rinse well again to remove the last traces of bleach. Then Starsan before next use, as usually.
I would clean it very well, using warm, not hot, (homemade) PBW or Oxiclean (Free), scrubbing/rubbing the insides with a non-scratching nylon carboy brush or non-abrasive (scouring) pad or washcloth. You don't want to scratch it, just have some extra friction when rubbing to remove any biofilm that may cling to the walls, bottom, rim, etc.
Don't forget to clean the stopper, carboy cap, etc. Anything that's suspect to harboring the infection.
You could add a small amount (~1/4 tsp per gallon) of Lye (drain opener) to your PBW/Oxi for some extra oomph, but
beware, wear proper face/eye protection and rubber gloves when using it, it's very caustic and even a small splash in the eye needs to be washed out immediately and thoroughly, and requires doctor's attention as it could cause blindness. I'm not overstating this.
Then you can do some "bleach bombing" afterward, followed by a good rinse out. Chlorine kills beer.
The following is for plastic fermenters, such as buckets: A sun batch!
Instead or in addition to bleach bombing, you could set those outside propped up under an angle, so bright sunlight can shine inside on all sides. UV light kills lots of nasties.
Right now I have 2 buckets outside, propped up under a ~45° angle facing the bright midday sun for over a week. Probably overkill, but I want to make sure. After transferring the beer, I hadn't cleaned them right away, and forgot about them, then discovered something gnarly started growing inside, the smell was awful... I just checked, they look and smell a lot better now. I would not hesitate to use them for today's brews, after another good cleaning and Starsan treatment.
