After some research, i founded (in Wiki) that space after a comma can
be avoided using: \setupmathematics[autopunctuation=all]. Sorry for
that.

So, only left second question. This is about opentype features,
specifically tabular numbers in math mode. This issue (i think) is
related to the commercial font that am using, because it have some OT
features enabled by default (eg: onum=yes, tnum=no and lnum=no).
Do you use Minion Math?
Curious is that i can only set lnum and onum but not tnum in math.
Does this work (untested)?

\definefontfamily[inlinemath][mode=base,lnum=yes] % tnum=yes etc.

\definefontfamily[…][mm][…][tf=features:inlinemath]

BTW: You can list all features of a font with "mtxrun --script fonts --list --info <fontname>".
