AVR-Chat

OK, was able to read the PDF version...

Your ISP looks fine - I have several circuits programming happily now
even without R3, R4 and R5. 

If I might be so presumptuous as to make some other recommendations...
First, dump that 7805. There are plenty of newer, more efficient low
dropout linears on the market now. Many of them can be sampled free from
TI. 

Second, don't tie up PB6 with a heartbeat LED, which (in the grand
scheme of things) is a task of relatively low importance. Remember that
PB6 is also the transmit pin for the USI, and your ONLY external
interrupt pin.

Just some food for thought...
