Sherie there are only 2 things i would comment on with your birth plan.

Firstly there is a reason why you are cannulated in the hand prior to the arm and this is due to the break down or collapse of veins. the further up a vessell you are cannulated the higher risk you have of having less options if the cannulation tissues or burst the vessells - deeming all lower peripheral veins useless.

Secondly you do not want an emergency c-section under a general. Depending on the reason for your emergency status this is usually the safest way to ensure that you as a mother is not threathen by your life! If it is for the babies sake you should be able to have a spinal anaesthetic however if it is your sake then it is often necessary to be put under a general anaesthetic to prevent cardiac or respiratory arrest in the mother if this is a threat.

You seem very definate in your birth plan which is great but i think you need to talk to your ob a little more to have a better informed decision regarding medical procedures so that you are not so dissapointed if this does occur.

Best of luck with the birth
