giggitygiggity, I don't think you should "interpret what they are getting at". There is no point in second guessing your ops manual. If it is not clear to you then you should seek clarification from management.
Personally I don't see a problem. The conditions in the TAF apply during the time group of the TAF or as modified by the change indicator (BECMG etc). BECMG 0810 CAVOK means the forecast is officially CAVOK after 10Z. For the purposes of alternate planning, if your ETA is more than 1 hour after that, you may plan on CAVOK at destination.
As for the wind, the mean wind forecast is the wind for planning purposes whilst gusts can be can be disregarded.
