big weight difference. 100lb is a lot in fighting. your punches will not be very significant to his body since he weighs alot more than you. what i recommend is you need to kick, not punch. go for his legs and do leg kicks. kick his leg and pull out, and do that multiple times to make him feel pain on his legs. you should not go f or his body. dont hit his neck or face, unless it is really necessary since he can counter you because arms are shorter than legs. you should watch out for a take down. he can charge you hard and slam you on the ground and god know what he will do. he can kick your face or throw punches here and there and you are done due to the size difference. street fight can be very different from UFC. use your elbow too if you can. 

After kicking his legs long enough, how do I finish the fight? Will I have to get him down, or will the leg pain make him yield?

If he lifts weight most probably he will have  concrete columns as legs (I know, because I have concrete columns XD), so kicking them is not a good idea.  Also if you have NO experience in martial arts, I dont recommend you to kick, because kicks are way to slow for someone who doesnt practice them.   Punches are always fast attacks so it doesnt matter previous experience.   If you are going to use kicks the must be fast, accurate, and most importantly STRONG;  ONE kick can end any fight if you know how to properly do them.  YOU NEED A TEACHER!!!  dont waste your time here, and go to someone you know that practice somekind of fighting sport.
