I praise your ability to speak english at all, it is my only language and I have enough trouble with it! :-/
Ok, about your question: This is a grey area. Lenses produce an analog image, and sensors are digital.
A 10 MP sensor has about 10 million possible points of data (ignore the RGB filter subject). Even a soft lens has a near infinate number of data points, being an analog device.
So, with any lens worth its lens-cap, will resolve more detail with more megapixels, but eventually the results are not noticable
However, the sharper a lens is, the more precise the detail hitting the sensor will be, giving each pixel it's own data, and therefore makeing a crisper image, even if the MP are the same.
Canon has some of the sharpest lenses out there, and I have gotten to use one of them quite a bit, the EF 70-200 F/2.8 IS II
On an 8 MP 30d this lens will outresolve My tamron 70-300 (at the same 200 MM setting)by a tad on my 18 MP 60d
So essentially my tamron is sending "blur" to 10 of my 18 megapixels. BUT If the tamron is put on the 30d, (8 MP) the results are a fair amount worse than on the 18 MP.
conclusion: Better glass helps more than more megapixels, But BOTH do help.
