Since there are literally hundreds of PICs to choose from there's going to be many that matches your needs, the limiting factor in this case will probably be if the device you're aiming to use is supported by the version of PBP that you've got.

Support for the 10F202 was added in v2.46 and it can certainly blink a LED but as a general purpose, low pincount, type thing the 10F series IS fairly limited (most of its RAM will be used up by PBP system variables so you'll have very little left to play with). You'll be much better of with a 12F series - like the 12F675 (v2.42 or newer) that you suggested or perhaps a more modern one like the 12F1840 (v3.0 or newer).

They all have internal oscillator so no external components are needed.

You can see in which version of PBP support for any particualr device was added here.

As for the programmer I really can't speak for the EPIC as I don't know anything about it but software for it seems to be available here.
