1. I have to set the bodyfont at the same time when I set a individual font for serif, sans or mono. This works fine for the the three text style but not when I try to switch to a different math font, which is frozen with the first \setupbodyfont command and can only be changed when I the main fontclass (created with \registerfontclass in \definetypeface) and the style value for rm (I need the 'rm' style to allow e.g. ss as document style).
This point is trickier than I thought, my two hacks work only when I use 'rm' for the main bodyfont style but it do no longer work when I try to set 'ss' as main style because with \undefinevalue{@f@st@rm}% I'm able to use the sans style as main font but the math setting is now ignored and with \undefinevalue{@f@st@ss}% I get the right math font and it's no longer possible to use a different style for the main font.
