Already did that. So there isnt any way to make this work right ?
If it doesn't have a bootloader, and you don't have an ISP programmer, or another arduino to act as one, then you can do nothing.
I wouldn't bother anyway, there is no sense in using an ATMega8, the 328 is what you want.
Unless you want to use "shields", then I would just buy a Pro-Mini from ebay, make sure it's the 5v 16MHz version. And a CP2102 based USB - Serial adapter.
If you do want to use "shields", then I would buy a Diavolino from evilmadscience.com and solder it yourself, because you learn something doing that, even if it's just soldering practice (and the Diavolino's look cool). And again, a CP2102 adapter.
