To program the chip in-vito can lead to problems because you connected some hardware to the pins used for programming on the 8-pin device. Programming and then soldering would work better.
The 8-pin device has got no SMP and I'm not quite sure what is with an external X-tal.
Yes, I would suggest you to create a MyCase.
I recently (1hr ago) had *VERY* good experiences with that, they gave me a phonecall within 10 minutes and solved the case!
