questions about the pattern I'm working on

[razorbackmama]

I'm being brave and attempting a sweater.

My pattern says to work in ribbing for 2 ins, inc 2 sts evenly across last row and ending with right side facing for next row.

The bold part is what I don't understand. Since I'm to just end whenever it reaches a certain length, not a certain number of rows, how do I know which is the right side? And how do I know which side it's facing? And what next row?

(I'm thinking I'll have a lot of questions about this pattern. )
