Firstly is HSS 'high speed steel' or 'high speed sync' (Don't bother replying to that one!)

Yes I don't need a higher shutter speed than 1/1000sec but my EOS still doesn't do that with flash which I need for indoor photography otherwise I'll get a black square.

Here is a photo I took with 1/200sec & NO external speedlight etc.

1/200sec

somehow I think you still don't understand everything.

When you take a picture, the shutter opens fully (which can be in the range from 1/200 sec to 30 seconds or even longer). When the shutter is open, the flash fires for a short duration (in the range of 1/320 to 1/6000 sec, see e.g. http://speedlights.net/2011/03/30/canon-430ex-ii/) - the duration is determined by measuring a short preflash (http://en.wikipedia.org/wiki/Canon_EOS_flash_system). So the flash length is set by how much light is needed. If you want to adjust flash intensity manually, you can do that on an external flash (internal not possible) but you don't set a time, but intensity level, since flash light not linear (it ramps up and goes down not instantly). The camera shutter speed has nothing to do with the flash at all, it just must open the shutter long enough to capture the flash duration over the full image. You don't set the flash speed with the shutter speed setting.

most cameras have such shutter limits, not just the 300D.
