My adivce would be to avoid the 100-400.  It is generally really good at the 
400mm end when the subject is close, but when the subject is further away (i.e. 
birds) its performance is not great.  I owned one for several years and really 
enjoyed it, and did get some publisheable shots from it. I have a 70-200mm now 
(which I used with a 1.4x extender sometimes) and it is MUCH sharper.  With the 
100-400 I rarely used anything less than 400mm but at the time this was a 
relatively cheap entry point to the 400mm length so I went for it.  

Out of the two options you've nominated I would pick the 300mm prime + tele 
combo, particularly if you intend to shoot birds and particularly if you intend 
to crop, where the extra sharpness would be of benefit. 

Cheers,

Stewart
