Hi Agus.
I think QGIS is mostly ignoring +twgs parameters. This is the root of
several bugs, and I think is one of the major issues to be solved.
Mentioned also in our bug squashing initiative:
http://www.qgis.org/wiki/Bugs#Projections
Unfortunately, it did not attract much specific funding jet.
All the best.
