In a few days i will get a 2x converter, i have never used them, do they offer good quality? I have 2 lenses: 35-70mm, and a 100-300mm, will i be able to use the converter with both lenses?
Can you give me any tip when using the converter?

I used to have a 2x TC that I used once. Expensive thing that way...
This was before the days of AF SLRs, things might have improved a bit since then, using that TC the camera would get the wrong aperture information from the lens, leaving all photos horribly underexposed.
I have since converted it to a 1" extension ring for macro work.

i have a f/4-5.6 70-300mm lens, and I was planning on getting a 1.4x converter to take to DFW with me...is this a good idea? i won't be using it all that much, just for those shots where i need a little bit more than 300mm...

a 1.4x with an F5.6 lens isn't a BAD idea - it's going to give you a max. aperture of F8, so if you already shoot mainly at F8, then you'll have an idea what to expect, shutter speed wise. The two things to bear in mind are: 1. you'll want a faster shutter speed than you're used to because of the extra length of the lens, and 2. you will lose some quality in the image.
I wouldn't recommend to anyone using a long zoom lens with a max f.stop of F5.6 to add a 2x converter (unless you're using a Canon IS lens, and adding a Canon converter) - shooting at 600mm with a max aperture of F11 is hoping for too much!
