Just doing a little shopping

Ok I'm over at amazon picking up filter cap pry tools do I need any thing special special for the oil plug? What about bleeding air out of the coolant system tips tricks or tools. I'm used to the old radiator cap or just the overflow but have found that these new systems are a bugger to get the air out. I am getting a scanguage just to monitor coolant. Any tips advice special tool you found you needed for regular maintaince.

Thanks
Jen
