1. Yes
2. The CS2 is the better center, period. The CS1 should "never" be paired with anything bigger than the 50. The CS2 goes with them all.

4. I wouldn't say that.
5. Yes and no. Depends what KIND OF BASS you wish to hear/feel vs your budget. I listen(especially at night while using Night Mode) w/o the subwoofer quite often on broadcast. DVD/BD I always turn it on. As you noted(if you looked them up) above, I have numerous sets of speakers. Except for the DCM TF600(which is no bass slouch itself), they can all achieve 35-ish hz...all by themselves.
So, buy your 3.0. Bookshelves or towers, makes no difference.
Even this...

Would be...
1. Huge improvement over the TV
2. For your ears, might be enough without a subwoofer.
Point is. Buy your 3.0. You can always add a sub.
