I agree with Pommy. The odds you have any infection is very, very low. I have brewed quite a bit and only every had one, which was really, really bad and was in Northern Brewer's Scottish 80 +/- Shilling and it was from the bung constantly falling out on a swampy indoor/outdoor carpet and being put back in. As you can guess I am not the most particular guy in the world about sanitizing my equipment, but I do my best with the inconvenience of my set up.
Beer goes through stages as it ages. One thing I can tell you is never to believe those "Ready In: BLAH weeks" you see on sites. It is always better to waite awhile. For instance NB lists their barley wine as ready in six months, if I am not mistaken. I wouldn't drink a barley wine in under twelve. It just will not be developed to its fullest. It will also have a bifferent taste at 18 and 24 months.
