I'm thinking all the sifting might be counter productive.  I like having some bigger lumps of organic matter in the soil.  It helps retain water and as it breaks down it releases nutrients.  I only sift my compost if I'm trying to get something out (like pine cones or needles).

I also agree with digitS about hand watering.  I think using the drip system will give you a better read on how well your soil is holding water.
