I agree with Allie in that you should find one Realtor that you are comfortable dealing with and stick with them as you will find that once you build a relationship both you and the Realtor will become more knowledgeable about each other and most importantly, the Realtor eventually becomes quickly able to identify your needs in new property listings.
I would start by calling upon some of those listings you have found here on Trulia and asking questions of the agent. Attending open houses (which are frequently advertised here on Trulia) is also a great way to get to know agents.
The only time I would advocate a buyer using multiple agentsis when you are looking in two vastly different areas. Full disclosure of the use of multiple agents is advisable. Seeing as you are from NY, should be desire to look in Monmouth County and Ocean County, you might be better served using different agents that specialize in those areas.
Feel free to email if you have any further questions as I do not follow Trulia posts (too time consuming, sorry).
