The other thing that bothers me about this power supply is how does adjusting the input voltage via a voltage divider affect the "regulated" output? I don't think that is going to work at all.
Yep look at the data sheet http://www.fairchildsemi.com/ds/LM/LM7815.pdf If you want to adjust the output voltage you do it through the 7815's ground pin. See figure 11 Page 19.
