Without looking at the manual, I'd say there is a lot of stuff (fuel lines, sensors, injectors) to remove to get to the lower intake manifold. I would be more inclined to remove what you can of the stud and try a thread repair/replace method mentioned above.

The timing belt is not too bad if you have done a fair amount of mechanical repairs. You really need to do a search on this site to see pics and details of 3.0 engine rebuilds. I can scrape together some links if needed. One of the hardest parts of the timing belt is removing the cam pulleys (high torque). It also takes some patience to align the crank and cams with the new belt.

If you're digging into the valve covers and timing belt you might also adjust the intake and exhaust valves. Starting to get a little involved isn't it? Neither is too difficult with the right tools and a manual. I have replaced the timing belt twice and adjusted the valves once.
