straighten the shifter with it off the bike as trying to straighten it while on it can lead to damage to the shift that's coming out of the transmission.
the bike dying when putting it into first is most likely a damaged side stand switch located near the kickstand.
dropping a brand new bike sucks as a newb, which is why most recommend a first time rider buy a used bike to start off with. you don't feel so bad when you damage a used bike.
heal up, read some riding technique books and get back on the horse when you feel the urge.
pictures of the bruised knee would be appreciated!!
