Welcome to the Q&A Forum

Hello again, From what I know, If there is no manual action, then you don't have to worry about reconsideration request. You have to clean up the backlink profile by the next Penguin update. Try to contact each webmaster first. If they don't answer in a decent time span then use the disavow tool. If there are too many links, then disavow the their whole domain. This should simplify your work. Don't worry about nofollow links, they hurt only in some very extreme cases -> watch this video from Matt Cutts about nofollowed links. Good luck!
