comment Divide line by length with QGIS
You can use a tool in the processing toolbox called "densify geometries at a given interval". You can found it at Qgis geoalgorithms/vector geometry tools/densify geometries at a given interval. The tool will add nodes at the interval desired. Bear in mind to use the processing toolbox in advanced interface.

comment How to calculate the distance to the nearest water source?
May be you can try using distance matrix (Vector/Analysis tools). Works with point layers where each point have a unique id. You can try the centroids of the "site" against the centroid of the water bodies. Other thing you can do is convert the water bodies (polygons) to line. Then extract the nodes (point layer), assign a unique ID (field calculator either $rownum or $id). You can run the site's centroids against the edge created with the nodes.

comment No Saga in QGIS 2.12
main thing if you install qgis via OSGEO4w in advanced mode (that you did not do it) you have to choose the other packages you want. Obviously this is not your case

comment Why is my area calculation coming out as 0.00?
you have only two decimals to store the area calculation, if you increase the number of decimals allowed in the calculation it will show something other than 0.00

comment How do I install qgis lyon with grass access
Using the "express desktop install" option in the OSgeo4w installer does the trick. Now you have 2 installations of Qgis, one with acces to grass. The acces is a bit different but it does work. I was able to open an existing an existing map set open layers and work with them without a problem. Now it is just a matter of getting confortable with the new procedure.

comment QGIS Least Cost Path
You must think about the cost raster as what are the movement impediments acroos your DEM. The factors that works as constrains coul be many. The simplest one is slope, for instance. You can calculate the slope from your dem (degrees or precent). In my field (archaeology) there are people that uses also the rivers and the slopes. I have seen even soils or vegetation cover as impediments. There is also something called the backpackers equation. In this regard you have to define which variable/variables are going to be considered.
