I need to learn the important way of working with the data having
different projection system for a single location. Usually the case is
between long lat and UTM projections. I set the region first with
g.region and then try to import vector data which is in long lat format
they do not get "on the fly" transformation in the GRASS and what I
find that they cannot be displayed in my region.<br>

GRASS does not do "on the fly projection". There are some good
explanations on the list why "on the fly" isn't such a good idea. {1}<br>

The second question is that is it possible to create two different
mapsets, one in Long lat and other in UTM for the same location and
then work upon these two simultaneously even displaying them.<br>

No, you don't work that way. You need two separate LOCATIONs, one for
UTM and a second for LAT/LON. Then use r.proj or v.proj to pull maps
from one to the other. MAPSETs are for sets of maps which are logically
related: same work project or in the same place, etc. But everything in
one MAPSET must be in the same projection and LOCATION.<br>

I hope to get some very good guidance on these issues.<br>
