I have a ETX-70 and Olympus Sylus u300 digital camera. I was thinking of using it to take some photo's. Can the tracking motor and gears of the ETX handle the added weight?

You don't say what you want to image - the moon or quasars! The camera should handle the modest additional weight but the obvious route is just experiment There are so many permutations of eyepiece and camera zoom so keep notes and good luck in your quest
I was hoping to try and get some shots of Emission Nebulae. If I could find an adapter, I would prefer to connect it to the camera port. I need to check the camera to see what the maximum exposure time is supported.

Your initial query here is already up on a Google search and, as close as I can get, to the review at http://www.steves-digicams.com/2003_reviews/stylus300.html shows 4s max in night-mode; modest f3.1-5.2 aperture zoom and autofocus only.
As the camera won't autofocus on dim objects through an eyepiece suggest you point cam skywards and half press shutter button to lock focus on near-infinity and without removing your finger hold cam to low power eyepiece with scope aimed at M42 [brightest emission object] and press shutter home for 4s [night-mode] exposure. Ok it's impossible to hold a camera still for 4s but you'll find out immediately if the camera is sensitive enough for this challenge. If there's something there - then mounting the camera properly and take dozens of 4s pics and stack together [for a longer effective exposure] via free software like DeepSkyStacker. Good luck.
