That is a fairly extensive list.
It's been mentioned before but there is a series titled
Science Fiction Masterworks, this encompasses a lot of what's above. Depending on how you get your books it may well be worth looking into. I love wandering through a second hand book shop and personaly I found that this series was such a good intro for me to some of the less recent SF, it may be harder if your borrowing though?
Over all it'll depend on what you find you like, if you prefer SF heavy on the science you may want to check out writers like the Robinson's Mars series as mentioned above and Gregory Benford, Greg Bear.
Benford's
Timescape, might be a good place to start with 'hard SF' or maybe Gregory Bear's
Darwin's Radio or
Blood Music, Le Guin is a must if you enjoy a book raising ethical considerations, IMO.
I'm reluctant to tip too many, as my own reading is still not that comprehensive but if you havent read
Dune I'll make an exception there, otherwise just check out what ever gets your attention
