When I import my PSD file into AE using (composition and merge layer styles) I lose many layer components. All layers are being displayed, but many shapes and layer styled texts aren't there. I will post images soon.

Not every feature imports correctly. You have to find parts that will not translate directly to ae and be a little creative.
If there was a link to the actual PSD I could probably tell you exactly what is going wrong. You could even resize it so that it's only about 100 pixels wide if the contents are proprietary.
