In the past I've used KisMac for this. <http://kismac.macpirate.ch/>

KisMac is a whole wireless (security) auditing suite and very  
comprehensive - I think its full features are kinda overkill for your  
purposes and that someone else write a simple stumber that would be  
adequate - but when you start it up it shows a table of which  
networks are detected & which channels they're on.

Ideally, if your neighbour's wireless is on channel 11 then yours  
should ideally be on channel 1, 4 or 8. I think that each channel  
overlaps the two adjacent ones, so spacing should be 3 apart.  
Different manufacturers of APs tend to choose different default  
channels - 11 and 1 are the most common, so it's as equally likely  
that packets from your neighbour's AP collide with yours as it is  
that they cause no interference at all.
