u wont use public transport here,esp if ur with fmly..cos mostly everybody with fmly has/actually needs a car..i dont know bout the package according to your experience,but remember that a n apartment wud come to around 6-10k according to your space requirements..But its also true that the rental rates have been dropping of late..guess u shud bargain for more by way of housing..
if u look at the other side,there are many ppl with fmly here doing more than survive on ur pay package,but in the end it depends on ur spending habits/lifestyle..and the competitive payscales in your line of work here in doha..
