I recently bought some of the cheap 'far east' 'STM8 Minimum development kits' off of eBay. They prominently feature the STM8S003F3P6 processor, but the 'kit' is essentially a break-out board with a USB plug for power.

I initially used the IAR C compiler for the STM8 and ended up buying some fo the cheap STLINKV2 clones, again from eBay. They work with the IAR product under Windows, and more importantly for me, they work with the stm8flash command line utility for Linux. As I am a hobbyist, the IAR product was pretty overwhelming (let me restate: I'm a Very Casual Hobbyist) and also wanted a Linux development environment. The SDCC compiler now supports (limited) STM8 application building, certainly more than adequate for my humble needs.
The SourceForge site has the relevant STM8 stuff for SDCC as well as some examples. I noted that the 'simple blinky LED' example relies on the ADC and interrupts, a tad exotic for my tastes.

Finally I found that the site by Mark Stevens called 'Silverlight Developer'
http://blog.mark-stevens.co.uk/the-way-of-the-register/ is a fabulous site, helped me to (somewhat) understand the low-level register setups of the STM8 products. I see that he's responded to your post and I can vouch that its a great site.
If you're running under linux, I don't think you can use the debugging features of SWIM.
Hope this helps
Good Luck
Terry
