Both of those woods are great - but please be aware that when working with iroko, some people find it to be a skin and nasal irratant as well the lungs! Great weathering properties (iroko) - goes a lovely grey. When working with the oak, try to use brass or stainless screws if you have to use any - otherwise you may get some black staining. Timber will always look great for a gate! Alternatively - if there are any cost constraints, try a good quality redwood then have it pressure treated.
Painted - use decent softwood from timber yard (not the nasty, twisted stuff from the DIY sheds). Properly constructed with appropriate joints, primed, 2 x undercoat, gloss finishes (always oil-based paint). It'll last for years - re-gloss maybe every 3 - 5 years.
I was very interested to see that the garage a friend of mine was having built was green oak framed with dowel assembly - the wood was coming from a local mill and he said the cost was very competitive.
