It will act like the pop-up flash, with the capability of more light. If you leave everything on auto, it won't be very different than the exposure you get with the pop-up flash (i.e., still ISO 3200 and such)

The guide number of a flash has nothing to do with what you set your shutter speed to.
Newer bodies do not support TTL, only P-TTL. You can get a flash with an Auto setting like the older AF540 or some 3rd party flashes that don't rely on "through the lens" tech. They have their own built in sensor.

1.) The flash tries to balance the ambient exposure with the flash acting as fill light. So, ISO 3200 in indoor low light isn't that far fetched for an ambient exposure. The flash can then use less power and acts as fill. If you want your subject to be the only thing lit in a dark vacuum, then you'll have to set the camera up to do that. Its can't read your mind.
2.) Most external flashes made for a pentax camera include P-TTL, the same exposure algorithm that the pop-up flash uses. Its utilizes the same ideas; pre-flash for metering and then calculated flash for exposure. Its just more powerful, gives you more options (like front/rear curtain), sometimes lets you shoot with wireless off camera flash, and allows you to set it to manual if you desire.
