2. For some reason, I didn't take any pictures between Bear Lake and Bierstadt Lake this year.  Here is one of the trail from last year.

When you get near the lake, the trail splits and you can go either clockwise or counter clockwise around the lake.  I recommend that you turn left and go clockwise around the lake.  Most of the trail around the lake isn't close to the lake's edge.  There is a sign that marks a good spot to go to the lake shore and get the best view with the mountains behind the lake.
