add objects with random prop. and track them w. camera

guess it can be done as follow:

  1. place null randomly
  2. add object from another layer
  3. change they properties
  4. track camera to it somehow

how can be done 1(how to change position, scale, etc properties)?
is added object will be in null, so null position changed, it changed too?

i found few topics with same subject, but all links to examples broken.

everything solved, almost as described.
rnd placement:
other properties with actions
camera with messages
