framing

I recently bought a 1920 house and i am planning on finishing the basement and i learned that the house had moisture problems in the basement and had mold growth in some areas but the last owner had the mold removed by a proffesional company. To prevent this from happening again I added extensions to the downspout in the gutters, i'm adding a 2 1/2 in. deep and 2 ft. wide concrete slab with a slope around the foundation to keep any water from going in, on the inside of the basement i fill the cracks on the concrete block wall and added a waterproof sealer to the walls and floors. is there anything else i can do to keep moisture out. and how do i know when is safe to start framing the walls.

Not quite the same question as raised earlier about insulating the porch. It's an enclosed porch with door, walls, window. I don't think the walls and ceiling are insulated but there is paneling on them. I'll remove a piece to see. The issue is with the floor of the porch. It is built on framed studs, no concrete foundation and on the outside there is just a lattice facing. I know I can insulate the joists under the floor. I can put poly on the dirt. The Question - how can I more permanently close in around the outside under the porch where the lattice is now so as to keep more of the cold weather out? My objective is to move the washer and dryer out to this porch. Presently, in sub-zero weather, the cat's water bowl and the stored onions freeze. :)
