Entrar de lleno en = ir al grano?
Get to the point, but what about "Vamos a entrar de lleno a la base de Arlong" - We're going straight to Arlong's base? So, with "en" it's to the point and with "a" it's "to" like a place. I don't suppose ir al grano could work with "to" a place though because "al grano" is kind of like, to the point. Gracias.
Another one: En aquel momento, los ojos de Aneki se fijaron de lleno en el cartel de Arlong.
At that moment Aneki's eyes noticed / saw immediately, Arlong's poster? Seems like that's what it means on that one.

En aquel momento, los ojos de Aneki se fijaron de lleno en el cartel de Arlong.
I would venture: At that moment, Aneki's eyes focused fully on Arlong's poster
Or possibly (and less literally): At that moment, Aneki's attention rested squarely on Arlong's poster
In any case, the expression "de lleno" is more along the lines of "wholly, entirely, completely, etc." Have a look at the RAE definition:
de lleno, o de lleno en lleno.
1). locs. advs. Enteramente, totalmente.
So, with "en" it's to the point and with "a" it's "to" like a place.
Just based on observation, I would suggest that this is not necessarily the case. If you do a google search for "entrar de lleno a" you will find plenty of expressions which do not describe a physical destination:
?México debe entrar de lleno a la producción de maíz transgénico ? Mexico ought to get fully involved with the production of genetically modified corn.
?Antes de entrar de lleno a este tema es importante señalar que un común denominador en el caso de los juristas de nuestro país, es que... ? Before jumping fully into this topic, it's important to point out that a common denominator in our country's jurist case is that...
I have noticed that many of the sources which used the preposition "a" were from Mexico which may reveal a regional difference in usage (or may simply be a coincidence).
