Increase Pattern Help

I've been knittig for a few years but never encountered a pattern that had steps like the ones I have questions on. I am making a simple dog sweater and here is where I have questions.

The pattern states:
CO 7 sts. Working in k1, p1 rib, inc 1 st each edge every other row 0 (0, 0, 3) times, then every third row 7 (9, 13, 14) times 21, (25, 33, 41) sts on needle.

Q1: I am making the 3rd size. Am I correct that I begin my first increase on the 3rd row? I know intuitively that this I understand the pattern correctly but just want to be sure there isn't a typo in the pattern.
Q2: Do I do the increase 1 st in from the edge like most patterns call for?
Q3: How do I maintain the rib pattern after the increase?

Thanks in advance for your help.

I would say Yes, you are correct on both counts.

MMario - Can anybody tell me what year it is?

MMario - I'm not divorced from reality - we're having a trial separation

Q1: I agree that you are correct.
Q2: I agree that yes you should do the increase one stitch in, but only on odd numbered increases. On the even numbered increases, you might want to put your increase two stitches in.
Q3: Wing it. After the first increase, your needle may look like K,P,P,K,P,K,P, etc. On the next increase you can insert a knit stitch two stitches in so that it is between the pair of purls.

Good luck,

Thanks all for your help.
