W: By walking through spring break, I managed to save up the 500$ for the trip to Canada this summer. How are you coming along?
M: I’m still a way’s off.

Question 1, What do "walking through" and "a way's off" mean?
Question 2, "How are you coming along?" = "How about coming along with me?" ????
Is "How are you coming along?" a common sentence you use every day? Any more similar expressions??
