I'll try to address your concerns one at a time:
1. Optimal shaving angle is around 30º. This translates to 1-2 spine widths from the face.
2. Pressure should literally be just enough to scrape the lather off your face. If you have to use more pressure than that your edge is likely not sharp enough.
3. By straight cut I meant the edge is straight across, or parallel to the floor. It works but is not the most efficient cut. Most of us graduate to other types of strokes ie heel or toe leading (also known as the guillotine stroke) or scything.
Here's a link to the library that will better illustrate my point.
If possible, try to hook up with a mentor or another member in your area. I haven't done a member search but I believe that Mvcrash is in Jersey. Send him a pm and maybe he can help you out.
