What are your planned dimensions for your space?

I wouldn't really say that four feet is tall, unless you meant a length of four feet and didn't say what the height was. Also, if your floor space is 4 feet by 3 feet, I don't think a 250 watt HPS will be enough light.

What is the width of your room? I didn't say it wouldn't necessarily be enough height, but simply stated four feet isn't what could be referred to in any sense as "tall".

If the temp gets to 80 or above your plants will die.
While anything over 80 degrees Fahrenheit starts to become less and less optimal, I think anything up to 95 degrees should be workable; at the very least, they won't actually die at anything less than that. Optimally you wouldn't want anything beyond 85, possibly 90 degrees. With higher temperatures you'd want more attention to CO2 levels and watering. Its the temperature of the roots which is the real concern, I would think. You've got to remember that a lot of cannabis thrives in regions along the Equator, and you'll certainly find temperatures beyond 90-95 degrees there (as well as increased CO2 levels to help offset).

I was planning to go 4 - 5 ft high, should i go all the way to 5 ft then?
Yes, most certainly go for five feet, and beyond if five feet is only an arbitrary limitation. You can help lower the distance you can keep the HPS from the canopy of your plants by using a cool-tube reflector that has adequate ventilation through it, as well as having a regular fan blowing on the canopy.
