If it is an LCD, you'll have minimal glare issues with almost any model. Be careful not to get caught up in the small things when buying a 37" or smaller. As far as a contrast ratio, there is no actual universal standard that all TVs are measured by. Each company basically has their own. As far as a refresh rate of 4ms to 5ms, you'd be hard pressed to see it on a 58" TV, you'll never see it on a 37".
It can be stressful, I've been there. I did a disgusting amount of research last year when I bought my TV. Three very basic rules to live by when buying an LCD:
1. Always buy 1 size bigger than what you think you'll be happy with. If you think a 42 will be good, buy a 46. Nobody has ever bought a flat screen and then wished they bought a smaller one.
2. Sony, Samsung, LG, Vizzio.
3. Don't listen to in-store sales people from big box stores. They are terrible.
