Personally, i'd put everthing in transports with red paint and extra armour. Last thing you want is to arrive piece meal, allows other armies to deal with you to easily and pick apart your units.
Want all your stuff to turn up at the same time and swarm the opponent. Orks can't hit with shooting for toffee, so your better off rushing them across the board asap and going for the assualt. Take burnas where possible as you won't have to rely on your dice hitting on 5+.
If you do have foot slogging units, hug cover and run rather than shoot unless the odds are really stacked in your favour.
