Those two a/c are much of a muchness really. Both completely useless in commercial flying and both pretty simple and easy to fly (perfect for pre-ppl)
If you are looking at going CPL in the near future just jump ahead in your timeline for a minute and have a look at which school you will do the CPL with. Then look at what aircraft they fly/what aircraft you will want to fly. Ie for CPL you need to do it in a CSU equipped a/c with a TAS of at least 120kts. If you want the best chance foroppurtunities after flying school then do it in a cessna preferrbly 182 as this is the entry level single used in commercial ops.
Now stepping back for a minute- say you will be flying a 182 in your CPL training then go down the 152 route. Even though they are completely different you will get used to high wing and cessna design features by then. If you are just going to be sitting on a PPL for a while then go the PA-28 route, 4 seats, bit more speed, more versatile etc. If money is tight and you can live with not getting anywhere too quickly then just go the 152.
And some one please reassure me there are jobs in GA for new CPL holders with 150-200 hours?
Yes there are.......but you have to find them!
can't help on the last question
