Dear Marco, thanks for your reminder! Yes, pgfplots now supports 2d polar coordinates, and it also supports cartesian input coordinates and contour plots inside of them. At least my early tests worked out correctly, but the whole things is not yet stable. You are invited to test it and report any improvement suggestions! I have just written documentation and examples, see the unstable TDS zip file (with its pdf manual) available from http://pgfplots.sourceforge.net/ . I hope the features are sufficient for your task and look forward to your feedback.
Note, however, that pgfplots does not yet support filled contour plots (only in an experimental stage). Concerning your question with vertical planes cutting through a 3d surface: this is beyond pgfplots. And the involved z buffering which is necessary to apply correct transparency for such a task is quite involved... I want to say: it requires quite some implementational work (and it will, in any case, increase the runtime requirements for TeX). Best regards Christian BTW: it is good you send this remainder, it encouraged me to bring the polar library a huge step forward (the missing ideas have been in my mind for some time, but I fixed a lot of them during the last days).
