Decorating and Design - help with lighting design for cathedral ceiling

We're DIY people and have this project which is proving to be a little more difficult that I expected it to be.
It is a great room 16X24 with cathedral ceiling. We have not sheetrocked it because I am undecided what kind of light system to have over the 16' wide walls. Sometimes I think I would like a valance with fluorscent lights behind it; other times I think track lights would be better if we cover them with some sort of crown moulding. Rope lights need transformer and I don't want to bother with that, etc...

My husband is doing the work, and he says I am driving him crazy because I cannot decide which way to go.
I want to have lights along the the two 16 foot walls above the windows so the lights will shine on the cathedral ceiling...
I worry the valance, sofit or cove or whatever itis called will protrude into the room and look awful.
Track lights by themselves seem too functional...
I will have a crystal chandelier, a couple of sconces and probably some track lights on the windowless walls...
Please help. I am hoping to be able to attach a picture...

While we await the pix, I like the idea of indirect lighting upward to accent the cathedral part. You indicate you will have other general lighting, so that's not a problem. The valance doesn't have to be a monster, as there are 1" tube lighting you can use, thereby minimizing its size. Rope lights don't need a transformer, as they are leds, but their light output is probably not what you are looking for.

Your best bet is to go to a lighting design center and let a professional help make your selection. You will be able to see the different options on display.

There are uplighting cornices available as well as uplighting coving lights. http://www.decorative-coving.co.uk/products.php?at_id=1&subcat_id=4&clear=1 (http://www.decorative-coving.co.uk/products.php?cat_id=1&subcat_id=4&clear=1)

I went to the website you suggested and I am not sure that I want that.
I have posted some pictures on the following website. The first two pictures show the walls I need help with.
Thank you...
