ok, let's sort the points you mentioned.
1) VST under ReWire slave
Sooner or later it will come, but probably more later because it has not such a priority like other things.
2) ReWire slave & ReWire master at the same time.
Sorry, but this is not possible. The ReWire specification just allows one (and only) master but an unlimited number of slaves.
i don´t know whats up whit the master out put cust not being able to aply live effects on what im doing in logic
Sorry, but I don't understand what you mean. Could you be a bit more precise?
