I had similar experience when getting back in to cycling a couple of years ago:
Yes it will be sore at first, but I have found these things useful:
Measure you sit bones - effectively sit on some corrugated card and measure distance between indentations

Play around with handlebar height - It's not just the height of the saddle which affects the pressure on your but
Some saddles are far more comfortable with the "nose" slightly up - I think Brookes in particular (once the nose was up and the handle bars set I found a Brookes B17 comfortable from new)
Also play around with the fore/aft position of the saddle so that your sit bones aren't sliding to an inappropriate part of the saddle.
I ride in jeans/shorts depending on weather (never more than 20 miles so far) and haven't felt the need for padded shorts, although something like Henry VIII's padded posing pouch could be impressive for onlookers I guess.
