You need to assess your total score, see http://www.cic.gc.ca/english/information/applications/guides/EG74.asp
For each of the categories you got 7, you can get 4 points and for each of the 5.5 categories, you can get 2 so total 12 points for languages. If you need more points for languages, you need to get 7 or higher in more categories or learn French.
CIC asks for IELTS. They do not accept TOEFL.
Skilled worker is undergoing some rule changes though. They are already working by the new rules so you can't escape them by applying now but they have not posted yet what they are exactly. The program may be tied to certain occupations in the future. Rules are supposed to get posted sometime next month.
