I have one last question. I think there might have been some starsan in my pot. I had let it dry overnight like the instructions said to and it was completely dry. However, my fermenter bucket still had some in it so I rinsed it out. Is there any way to tell if I did not remove all the starsan?
Not sure what instructions you're refereing to. Star San only kills microbes when it is wet. Further, it is a no-rinse sanitizer - not a cleaner. This means that a) you shouldn't be using it to clean your pot - PBW, OxyClean Free or regular dish detergent are probably the best things for that; and b) you shouldn't rinse it out of your fermenting bucket.
You don't have to fill the bucket up to the top. Do a 1/4 oz Star San concentrate with 1-1/4 gallons of water. Use a spray bottle full of StarSan (at normal dilution) to thoroughly spray the bucket lid and the rim of the bucket. Put the lid on and shake. The Star San solution will foam up, coating every surface. Leave it like that, with the lid on until you're ready to transfer the wort to the bucket. Then remove the lid and dump out what ever Star San will come out - not all of it will, but that's okay. Transfer your wort into the bucket. Pitch your yeast and give the lid a few more sprays before sealing it up.
Star San is a pH based sanitizer, meaning it only kills microbes when it's at it's normal strength. The small amount left clinging to the sides of the bucket or in the foam in the bottom quickly gets diluted by the wort, so that it's no longer strong enough to kill your yeast (in fact the yeast can utilize the phosphorous it contains as a nutrient).
