Thanks for all the input. I am actually trying to decide between the equipment mentioned in the OP for starters. I am pretty sure they will be fine for all my local needs. beyond that, i am trying to see into the future as far as what i will need for colder dives (I.E. Central Cal and B.C.). Couls you elaborate on the 'Ice Cap"? I am new to dry diving.
I also need to consider that I will be taking pictures in deciding on a glove.
Thanks again...
Sorry for the delay in responding, Danny. I wasn't paying attention....
An "ice cap" underhood is usually made of 1/8" neoprene with no nylon lining so it seals extremely well, especially on the face. Also, it covers so much of the face that the only skin left in contact with the cold water is the outer edge of the lips.
Since the lips have such good blood flow, they tend to stay warm even when exposed to ice-cold water. Seriously.
With a typical hood in water temps less than about 45F degrees, the area adjacent to the lips isn't adequately protected and the tissue can get very cold. That can quickly cause reduced blood flow and further heat loss and eventually the whole area gets painfully cold or even numb, including the lips since their blood flow was reduced upstream of them.
I use a Henderson ice cap under a DUI Warm Neck Hood. That hood also has a 1/8" neoprene face seal with the smooth side toward the face. This combination seals and protects so well that I've been quite comfortable in 35F degree water for well over 90 minutes.
In fact, the seal is so good that I often find the hoods are mostly dry underneath, even after long dives! I sprinkle talc powder on the ice cap to make the regular hood slide on more easily and the powder will still be dry when I finish the dive!
I like the ice cap so much that I use it on almost all my dives below 70F degrees. No more cold cheeks or numb lips when dropping below the thermocline!
For winter diving, it's been indispensable and amazingly warm.
Aside from increasing my undergarments, keeping more air in the suit and avoiding constriction, the biggest improvement to my thermal protection was adding an ice cap underhood and dry gloves. Now every dive is wonderfully warm!

HTH. Enjoy!
