OK-my apologies. I mis-read your post as saying that you continue to confuse creatinine and creatine as the same thing - which upon re-reading you clearly now understand. My error.
It is true, however, that creatinine is the break-down product of creatine. However, oral ingestion of creatine will not necessarily increase your creatinine output - since the creatinine clearance test is often part of a ratio that looks at kidney function - so, if your kidneys are healthy, I wouldn't assume that creatine supplementation would alter your creatinine profile.
As for vegetarians having lower creatine levels - that is my understanding also. Some people feel (not certain if there is science to back this up) that heavy red meat eaters have naturally very high muscle creatine levels (since there is alot of creatine in red meat) and therefore can often not see much of a result from creatine supplementation. Vegetarians, on the other hand, have lower muscle creatine levels and therefore can respond very very well to creatine supplementation.
Hope that this answers your question.
