Hi kevinz,
I would suggest that you NOT use alkyd (oil based) paint on the walls. You can get a great finish in the sheen of your choice with an Acrylic latex wall paint. Alkyd paints are still used (by some painting pros) on windows doors and woodwork. However, Acrylic latex enamel trim paints have come a long way in the past few years in terms of "flow out" and uniformity of the finish. You might consider Ben Moore's top of the line Acrylic latex enamel for the windows, doors and trimwork.
I suggest that you prime all of the windows, doors, and woodwork regardless of which paint you choose.
The roller nap marks on the walls are almost impossible to sand out. The best bet is to skim out the walls with drywall compound. Prime the walls with an acrylic primer/sealer BEFORE you apply the skim coat and re-prime the skim coat after you have feather sanded it.
A 2 1/2 or 3 inch thin stock nylon/polyester brush works great to cut in wall and ceilings, it can also be used for the woodwork if you decide on acrylic latex trim paint.
We use Purdy brushes and roller covers.
Should you decide on alkyd ( oil based) paint for your woodwork use a 2 1/2 or 3 inch white china bristle brush. Wooster makes some good ones.
If you are going to use a wall paint with a satin or semi-gloss sheen (shine) use a 1/4 inch nap roller cover. For an eggshell, velvet or flat sheen use a 3/8 or 1/2 inch nap.
