Whenever I take hydrometer readings in the trial jar, the beer always looks carbonated.
Well, yes, the beer appears carbonated, especially if it's kept cool in the fermenter. That's why there are priming charts telling you to add less sugar if the beer is under 60 degrees. CO2 tends to remain in solution when the solution is colder.
I think you'll have very flat beer if you don't prime. If the beer is finished (as proven by FG readings) and the yeast have eaten all of the fermentables, the shouldn't be any available sugar for them to ferment. Racking will cause some of the co2 already dissolved in there to come out of solution, as well.
If your beer was overcarbonated last time, either you didn't wait until fermentation finished, or you added too much priming sugar. No other possibilities at all.
