If you plan to do your upgrades within the next 4 months, you'll want to 
target 8.2.4.  If you plan to upgrade after that, then 8.3 is the version 
you'll want (it is currently expected to be released around July). 

You should be aware that upgrading from 7.1.x versions is likely to be a 
somewhat intensive process since, while it should be backwards compatible,  
recent versions of pg_dump almost certainly hasn't recieved much testing 
against 7.1.x versions. (I'd almost recommend upgrading to an intermediate 
version like 7.4.x, but it probably isn't worth it... just make sure that you 
keep a copy of your 7.1 databases running until your done testing, and make 
sure to test your applications thoroughly.  Also don't forget that any 
applications /drivers/ libraries that are built against 7.1 should be 
updated / recompiled against newer versions as well. HTH.
