CC-mode gives you a lot of options for controlling indentation.

  M-x Info-goto-node RET (ccmode)Commands RET

The subsections "Indentation commands", "Minor Modes" and "Electric
keys" will probably be the most relevant for what you're trying to
accomplish.

For (1) something like

 (setq c-basic-offset 8
       indent-tabs-mode t
       c-insert-tab-function 'tab-to-tab-stop)

 (setq c-syntactic-indentation nil) ; maybe, or maybe not this one

should be close to the behavior you're looking for. 


For (2), try

  (c-toggle-electric-state -1)
