Fantastic! That looks much better, good detective work!

Yes I agree with you, a little lower and you'll be golden. As an example, your z endstop should be set so that it trips/clicks when the end of your nozzle is about 70% of your desired layer height above the glass. You might find that you need to get the nozzle even closer to get a good stick but think of the nozzle as smoothing that first layer of plastic down over your glass bed.

Here's my bed leveling procedure in case it's any help. I'm sure you already have one!

1. Connect to pronterface and home your axes where your nozzle is all the way in the corner (probably the back right one).
2. Make sure your nozzle is about 5mm away from touching the glass.
3. Adjust the z axis and get the nozzle about 1mm away. Then start lowering it at a 0.1mm increments in proterface and slip a business card or feeler gauge under the nozzle.
4. Feel under the nozzle as your lower it and stop when there just a little resistance between the glass, business card, and nozzle when you try to pull the business card away.
5. Loosen and adjust your z endstop upwards so that it clicks against the axis then tighten it back down.
6. Move your z axis up a few mm until the z endstop unclicks and lower it slowly to see if it stops at your desired height, fine tune if necessary.
7. Once your happy with that corner, lower the z axis until it stops, then move your x axis towards the middle and watch the space underneath the nozzle. If it's getting less and less, adjust the bed at the corner you're heading towards until your sure the nozzle can make it all the way there without scraping along the glass. You may find that if you're not able to adjust that corner or it's bending your heatbed too much. If this is the case, try to make sure the x axis is level across the top. You can adjust this by turning the z rods on either side to tilt the x axis.
8. Once this corner is done and you can feel a little resistance on your business card in this corner and you are happy with height under the nozzle in both back corners repeat this procedure with the front two.

You might find that the heat during a print slightly changes the height under the nozzle but this should get you started in the right place.

In the future, definitely try out clough42's improved z endstop design found here. Adjusting the stock makerfarm endstops can be pretty tricky. This will help you easily fine tune even more and it's fantastic! http://www.thingiverse.com/thing:336665
