Hi Jimi,
Since you posted this to the "Morality and Daily Life" forum, you probably want to discuss it in these terms.
So, what is morality/sila to you? Is this a set of rules to follow or tick off, in order to get a perfect or good enough score? Who is the score-keeper, and why is this score kept? Or is it your desire to change your circumstances to have more "good" and less "bad" in them, and your concern is less with having a perfect record than with living a good, useful life (for arbitrary, but pragmatic values of "good" and "bad")? Or do you want to create circumstances conducive to tranquility and wisdom, and just want to avoid the hustle and bustle of violating society's moral code? There are many ways to approach this.
Then, once you have an idea what you want to get out of morality/sila, you will have a much better view of how your reading habits fit in with these goals.
Regarding the nagging feeling - well, investigate it! That's more in the realm of insight training, of course, and so slightly off-topic here. Anyway, one way to proceed would be to write about it. Don't try to reason your way through it, rather, ask yourself, what is the true reason why you are having this nagging feeling. Once you come up with a reply (doesn't have to be an answer), ask again, in what way is this the real, true reason? And so on. Again, this is not indulging in content: think of it as a noting practice with very elaborate notes.

There are other ways to investigate the nagging feeling, like trying to locate it in the body when it arises, or trying to find out how long it lasts, or finding out what your relationship is to this feeling - is it yours? If so, why don't you like it? Etc.
Oh, and I go trolling on the German Christianity usenet group occasionally - many Jesus sayings are so clear and obvious to me now, and chatting with Christians about them is fun sometimes. Nothing wrong with that, I think, even if it doesn't seem to lead anywhere.
Cheers,
Florian
