plot legend with filling

Dear group:
I have two arrays of numbers, think of something like this: 
v1={{1.15,0},{1.15,3},{2.15,1},{2.15,7},{3.15,3},{3.15,9},{4.15,5},{4.15,7}}
v2={{1,1},{1,5},{2,1.8},{2,6},{3,3.5},{3,10},{4,4},{4,6}}

I want to make a graph with these two arrays, where I get:
a. A line from the x axis to each point in each array
b. A legend, with say v1 red and v2  blue
c. Each array has its own filling style (different color, thickness, etc.).

The problem is that I can find ways of plugging in two of these characteristics, but not all three. For example: 
<<PlotLegends`
p1=ListPlot[v1,  Filling->Axis, FillingStyle->Directive[AbsoluteThickness[4], Blue]]
p2=p2=ListPlot[v2,  Filling->Axis, FillingStyle->Directive[AbsoluteThickness[4], Red]]
Show[p1,p2], but then I did not manage to find the way of using Show and PlotLegend at the same time.

Or I can put both arrays into a Listplot command, but then I did not find how to attribute a different color AND thickness to the filling of each array.
I'm using Mathematica 8
Can somebody help me?

Francisco
