Murph hit the nail on the head for my experiences.
Our drysuits have built in booties. We wear thick smartwool socks on the inside and oversize crocs on the outside. This is perfect for us. If you wear shoes that are too tight, your feet will be colder.
The hands have been tougher to deal with. We dislike every neoprene solution we have tried as well. I think you are behind the 8 ball to begin with due to the drysuit wrist gasket decreasing the blood circulation in the hand. Though I can't really rate it as "good", so far the best solution for us is pictured below. It is also the cheapest. A pair of PVC gloves from the home builder supply store lined with a pair of warm work gloves. Nice-n-easy to put on and take off. The blue glove has a synthetic fleece lining so it still gives some insulation when wet. It probably isn't the safest thing to do, but my last couple cold outings I went gloveless and just pulled my hands inside the drysuit when the became uncomftable.
Even with the drysuits, duofold long johns, fleece drysuit liner...we set a 50 deg air temp limit and don't go out in high wind during the winter. I have never seen the water temp drop below 38 degs here so we only factor that in deciding what to wear under the drysuits. Even at 50 degs, the face and neck can start to get cold - we may purchase something this year for coverage of those areas. The way the weather has been here lately, we might have to break the 50 deg rule if we want to get any water time in. The neck/face coverage would help a lot if we do.
