I took my standard RM out on Friday when the Met Office claimed the temperature locally was 34°, and had no overheating issues. The run included several second-gear gradients, but no significant traffic, certainly no significant stationary moments. The story may have been different if I had encountered major hold-ups, but I do know that my car runs significantly cooler than a number of other local Sevens.
But basically, no you are not expecting too much of your car! Your fuel problem sounds like evaporation probably caused by your engine overheating, rather than a weak mixture causing the overheating; I would suggest the first likely suspect is the radiator - has it been recently re-cored, or is it an elderly matrix that may be furred-up? Second area to investigate would be the waterways in the cylinder block and head, again prone to blockages.
