I had a lesson yesterday and my coach told me my main area of concern is that I basically don't use my legs enough and I use my body too much.  He said my push away and swing are consistent and good.  I don't really force the downswing  My timing is good but I fall off balance(and possibly have other problems) because instead of driving forward with my legs and body(or even if I try with my legs), a lot of the time my upper body dips down to the right.  It doesn't seem to help when I throw the trail leg over a certan way either.

I don't think I've always done this which kind of confuses me because I haven't always been the best at using my legs either.  I'm over 6'0 so I almost feel like that's contributing to it because maybe I'm trying to get my release closer to the ground that way.  I'm wondering if there's any mental tips to help keep my body from doing this, or if there's possibly something else triggering it.  I'm playing around with 4-5-6 steps and where I stand on the approach trying to find my sweet spot too.

I kinda noticed that too, and I've tried to step in before.  I almost always end up hitting my ankle, I think it's because the ball is already not far from it.  There a some shots that I actually feel the ball brush my ankle.  I think I have to fix the upper body thing before stepping in is an option.

I have read it two or three times before, I'll take another look.

Hi Justin,
Here are a few things to consider.  KingPin mentioned that your slide foot is not in your center of gravity, which is one thing.  There are probably a few things causing this.
I tried to evaluate your video a little and here are a few things to work on.  Your non-throwing arm is doing nothing.  Have a look at some good bowlers or PBA pros, you'll find that the other arm plays a role in balance.  Kind of like a tight rope walker, always uses 2 arms outstretched to balance themselves.  
If you pause the video at your delivery, you will find your whole upper body shifted to the right.  That makes it very difficult to be balanced...and have leverage.  Your head should be just to the right of your slight foot.

Watch this video of the 2009 US Open.

At around 2:30, you will see one of my favorite deliveries from Richie Wolfe.  

A couple of things to highlight:  
1. watch what his non-bowling arm does.  It will be equal and opposite of the non-bowling arm, i.e., the higher your back swing is, the lower the opposite arm is, and vice versa.  But it is more or less stretched out.
2. Watch where his head is in relation to his slide foot.  It's just slightly to the left (he's a lefty).  So you're spine should be a little more aligned.
I won't go as far as to make it straight up and down as this is more from the classic days.
3. One of my favorite parts is what his back leg is doing.  Watch how he keeps it outstretched and on the ground.  He is perfectly balanced.  This is some thing I suggest do look at.

Of course, if you have a coach, you will certainly get differing opinions so you need to trust what you're coach is trying to teach you.  This is hopefully supplemental and not in conflict.

You can also have a look at my article and coaching video exactly about this topic of leverage, upper body vs lower body.

Good Luck!

Mo Pinel, looked at one of my videos and told me that I shouldn't keep my non-sliding foot up in the air, because it causes people to hit up on the ball...but outside of PBIII I can't think of any pro that keeps their non-slide foot on the ground.
