Your best approach is to talk with her about the Bible, what it says on these issues and study it with her. It may be if you can show her where the Bible, and accepting it as the word of God, disagrees with the JWs on some of these issues, then maybe she will consider the peculiar doctrines from the JWs not in line with the scriptures but maybe not. I suspect it will require you to really take the believer's perspective seriously and come up with theology from a believer's perspective that disgrees with some of the JW ideas. In fact, it may take you yourself taking the things of God much more seriously and really seeking God out with an open mind. Otherwise, what do you have to offer her?
Materialist presumptions?
Take it slow. Offer to read the Bible with her and talk about what it says.
Admit that sure, God can and does communicate with anointed people but why only the JWs. What about the signs and wonders in the Bible? Are they happening with the JWs, for example? Just a little thought since the gospels promise to "confirm the word with signs following."
I am sure she has an answer but it may not stand up to biblical scrutiny. Keep in mind she probably accepts the Bible as God's Word, and you can talk with her about, hey, what about before the JWs came along. Didn't the Pope also say that what they said was more important than your direct experience and reading of the Bible.
There's a lot of angles. Take it slow and be peaceable and if you are just wanting her to become secular, give it up. You most likely will not like the result. When you come across biblical statements contradicting JW theology, ask her to pray about it. Heck, if you can, pray about it yourself too.
But keep in mind if you are trying to convince her God isn't real or evolution is true, ask yourself why you are doing that? You loved/love a girl that is a believer, not an unbeliever. Trying to make her into someone that takes the doubting, skeptical perspective will probably harm your marriage. You married a woman of faith for a reason. it's part of her make-up and constitution.
