Heat Pumps and Electric Heating - Questions about electric heaters

I recently finished a 500+ square foot room in my basement. I decided not to heat the room with my furnace, but to use electric baseboard heaters instead. I also decided not to do the permanent baseboard heaters. So, what I ended up with is tough decision. I could have purchased 3 electric baseboard heaters (the type you plug in) each heating an area of the large wide-open room. I ended up buying an electric wood stove (the kind with the fake wood and fake flame, but the heater fan on the underside) and one portable heater. The wood stove says it heats up to 400 square feet and the portable heater says it heats 200 square feet. My questions are:

1. If I place them properly, does it work that way that a heater for 400 sq. ft and a heater for 200 sq. ft should comfortably heat a 500 sq. ft room? Or am I just wasting money?

2. The wood stove doesn't have any warnings about what it should sit on. I'm a little concerned because the heat fan on the bottom side of it blows the heat down and out. My floor is carpet. Should I worry about having that thing sitting on a carpet floor? I ran it for a few hours and the carpet got pretty hot. Not scorching, but it made me wonder.

Thanks!

I would think that if placed properly they could get the job done but I have never seen anyone do it so I cant be 100%. Can you tell me what the BTU rating for those two heaters are?
