Hey Jim, answers for you:
1) Did you download or buy over the counter? Im not sure about instructions for the download version but the manual in the box version should outline the basic, not crane operations though annoyingly, look to the controls section in the options for those.
2) Number keys 1 through 3 are the view controls now, 1 being Orbit, 2 being Helm and 3 being Free Roam.
3 & 4) Along the bottom of the chart display is a transparency bar, the further you slide this to the right the more visible the chart becomes.
Hope I helped in someway, if not im sure one of the mods could help also.
Regards,
Andy
