So, I wanted to grow my highland nep. burbidgeae with the sundews, in high humidity and drops down to around 55 at night but do you think that they should just be in separate areas?
Also, if the plants are really close to the lights (4-6 inches), won't the heat burn them if there isnt any glass?
I haven't grown this particular Nep but I would keep them in separate environments. 4-6" is generally a good distance from plant to artificial light and there shouldn't be any heat generated by the light, assuming you are using fluorescent lighting. Which sundews do you have? Some are tropical. Some are sub-tropical. Some are temperate. Depending upon what they need is the best determinant as to whether they can be kept together.
the sundews are subtropical are sub tropical. I really liked the shelf idea where the plants are just on a shelf with a light over them (no tank) but I was wondering if there is enough humidity for highland nepenthes this way.
Hmmm - I glanced through the replies and think I need to disagree w/ the responses (or at least qualify them as possibly being overly simplistic).
Typically a healthy Drosera will produce significant quantities of dew. If they didn't do that in nature, they'd be unable to perform their function and be at a disadvantage to their brethren. The replies that I noticed (such as strong light, air circulation, humidity, etc) can all contribute to the plant's health but may not be the determining factor in how healthy a plant is. Since many dews grow in open sunny areas, strong light is often a factor in their health but some plants may need add'l factors like high temps or high humidity or possibly even the correct combinations of these or other factors.
To state that changing any one factor is the holy grail for determining dew production for D. arcturi, D. lanata, D. linearis, D. schizandra, D. regia, etc would seem to be misleading. Finding the specific requirements to fit each plant's needs is what we try to do in growing them. Dew production is one characteristic than often provides us an insight into a plant's health / 'happiness'.

are 40 watt T12 tubes sufficient for my plants? do I want T12 or 8,? or do I need to get compact lighting?
your nep should do fine in you can provide a night time temperature drop for it.
As for the dews, i did a little research, D. hamiltonii has a reputation for being pretty hard to make dewy. So don't be surprised if that one always looks a little pathetic.
