I have large pine trees and want to plant Hosta or some border bushes and plants, maybe perennial flowers in the pine straw under them.

Pine trees tend to have acidic soil, but most plants can handle the acidity. The real problem will be the fact that the tree will suck up all the water. You will need to make sure the plants under the tree get extra water to offset this.
