Legs quit hurting???  I think happens about the time you quit sweating.
 
Just ride. Enjoy. Ride insanely long distances that you'd never have thought possible on your old bike. The speed will come when your body is ready for it.
 
You might want to get with another Corsa rider to help get fitted to the bike. There are a few little tricks that might help things along.

Not sure about the legs hurting -- maybe you're  "mashing" more than spinning, but it would take some visual observations to tell....
 
About the seat distance, this may be related to your shoe cleats.  Most recumbent riders move their cleats (assuming you're using SPDs or related "clipless" methods) as far towards the heel as they will go, so you're not pushing with the ball of your foot.  If you haven't done this, and are still connected more towards the ball of the foot, this may be the reason.  However, it's not an absolute adjustment, really, it's just a starting reference point.  If you need to move from there to make it work, move!
 
Where do you live, and where/when do you ride?  Tell us more!

As typical, everyone is different. Even likely moreso than on a road bike, a Corsa has a lot of ways to set your riding position. Most people (including me) start out with a pretty closed riding position that favors a higher cadence, using mostly just leg muscles. As your glutes and lower back muscles get stronger, you can assume a more open/aerodynamic position that is harder to spin with but much faster. Then you discover your pull muscles wherein your distance/endurance lies, and then you go on to using both most of the time, with possibly a predominance towards pull muscles except when climbing, sprinting and especially rolling over hills. In this new position your glutes don't rest much on the seat except when you slack off. That's one of the reasons highracer riders seldom get recumbutt - it's not really resting on anything when you are cranking. With your glutes off the seat much of the time it really becomes inconvenient to spin much though. Then is when you really start working on technique. Riding century after century, you have enough time to start analyzing different pedal strokes; what stresses your ankles and what doesn't, what stresses your forearms and wrists and what doesn't (yeah barcons!!!), what to do about supporting your big ole noggin laid way back like that all day long. Then out of the blue you ride halfway across the country and back averaging an insane century a day.  Then you wake up one morning after foolishly riding for 357 miles in a stupid race that a bunch of your so-called friends talked you into, totally unprepared and ignorant, but yet, to your complete and utter amazement, you somehow finish. Then one day the stars line up and you get that special tailwind century ride. You blow through entire towns at 30-35 mph floating along with traffic and get a weird sort of tunnel vision experience from cranking so hard and going so fast for so long.
 
Your Corsa has become your friend. An amazingly wonderful and totally insane friend.
 
Then you get an even faster and more totally insane speed bike and have to start all over...
