At the point where my mouse is hovering.... what do these #s mean:
Sum (XMR): 110602
Sum (BTC): 1793
Does this mean that for the XMR price to reach 0.017, the market needs to buy 110602 XMR that is worth 1793 BTC?
yes that is right. in other words there is currently a 1793
BTC resistance against reaching 0.017 price although you have to keep in mind that these numbers will change when the price changes because these orders can be closed and opened so in other words reaching 0.017
BTC price may only take a 20

What is all the information I can gather from this chart?
does the size of the red side vs the green side tell you anything?
If the green (buy) side is much larger then there is more buy pressure and more likely that prices will stay or rise higher? Or can you not come to that conclusion with market depth
you know most things yourself already
the market depth charts or the orderbook chart is a good graphical way of seeing how the market is and which way it is leaning is it towards a rise or a dump.
you can also see the "walls" on this chart easily. when there is a big vertical rise in the chart instead of a smooth diagonal rise it means there is a big ass wall which will prevent moving past that particular price up or down.
e.g. you can see a tiny wall on ~0.003
