Given that you have some flexibility with foot print and you will be dumping into a hopper a cleated belt is probably the cheapest and easiest to implement option. Vibratory feeds are really good if you absolutely need to have the components aligned and your through put is low (ie bolt feeders...
1. Good for large batches with longer spaces in between. May require integration of a slightly more complex control system to start and stop the bucket more precisely, or a dump and accumulate strategy.
2. Depending on flow rate can be continually running, no space required between batches...
prost you are correct in the applicability, I am assuming that if he is looking at contact stress than he is not interested in other failure modes (or is handling them separately).
For the OP, if you are concerned with failure of the joint remeber that for "pin in plate" there are a half...
IMHO The easy answer is that if you are not comfortable with the technique than it is not OK as a tool. As a responsible engineer you must be confident that you arrive at the right conclusion based on your method.

Depends what your application is, for general strength analysis it is usual to approximate bearing stress as simply the load over the simplified bearing area (hole/pin diameter X hole depth). Anything more than that and you are getting into some nifty equations or FEA.

I pretty much agree with CoryPad
1. Yes, though some plastic types much less than others (ie PPS or acetal is better than cheaper alternatives)
2. I believe that a glass filled plastic (PPS, acetal, delrin) will be more stable than a non-filled alternative.
3. You can use some MODs...
100,000 should be no sweat. try running a simple analysis first to rule out some problems, then slowly add complication. ie try everything as fixed and put in some simple rigid boundary conditions. Start with a nice open mesh to speed things along until you figure out what is wrong.
Once you...
By the sounds of it you are interested in the stress levels in the adhesive. If this is the case then it would be a good idea to include the adhesive as a solid. There are various methods to accomplish this depending on what software you are using.
Just be careful, for most element types...
