You must have straight line shots between the servo and moveable surface: again wrong, if you use the proper guides you can change directions a great deal to enable routing the pull-pull lines around structure or to make exit points in a better location.
Yep, you're quite right. Have a look at the control runs on early fullsize aircraft (IE WW1) - aileron cables routed from the stick out through the wings, and tail control cables on pusher aircraft (IE DH2) routed out around the prop to the tail.
