I got used to r/clicking(shame poser cant lol ) never tried the VSE yet or the BGE, but really want to play with its physics so will get round to that one day. Most of the other stuff I have touched on just to get the basics and find a lot of the time once you know a bit about "A" part "b" makes more sense, guess theres just sooooooo much to learn. Blenders cloth is pretty much the same as posers and you DONT need the VSE to do dynamic cloth just the timeline, hey an if you dont like the sim just rewind tweak the mesh an run again much more fun then poser. Dont think you'd like the way I work in blender ;-) , I have 2 monitors so one does all modeling (perp,top.etc) and the outliner and properties other has graph node uv editors and timeline an a bit of room for anything else I fancy

ok your prob with moving the VIEW with middle mouse takes it out of camera mode(numpad 0) , to move cam in that mode make sure cam is selected then use R T or G, handy for tweaking but if you need a major move on the cam then best to pop out of cam mode an just push the camera around, another trick thats handy is to add an empty then use a damped track on cam(can use track to but damped is better lets you rotate the cam if u need to get horizion level)
