There are sertintly things in the Bible that arent easily understood, like the parables for example. But greek couldn't help at all because they are things that are spiritually discerned.
Just because you can't get something from a verse in the Bible, doesn't meen that there is something wrong with that verse. It could be that that verse, what ever it may be that your having trouble with, is a verse that God wants us to seek him directly with, he may want us to pray, to spend time studying it.
The bible is the most amazing book ever written. How else can you explane finding something speacial from say romans that you never saw before, even though you have read romans 900,000 times.
I don't see anything wrong with using Greek or hebrew, or a Concorance, as long as you remember that the best source for understanding something is the Lord himself, the author of the Bible.
