Sql 2008: sleeping thread,open transaction, open locks......

I can see from sp_who2, dbcc opentran, dbcc inputbuffer, etc  that our sql server has some sleeping connections that are holding open transactions (along with some X locks) for long periods of time. I'm not sure the DMVs\tables to use to get this info but I need a query that returns this info when run:

<Datetime>

SPID

HostName

ProgramName

DBName

output of dbcc inputbuffer(<spid>)   -- the sleeping query last running

State  ( for state = "sleeping")

trancount ( if > 0)

BlkBy

X-lock (if lock is of type "X")

<time X lock held or something similar>

I'm focusing on X locks assuming that sleeping transactions with "S" locks are OK. (Maybe that's a bad assumption, not sure).

I will store the output in a table to gather historical data about this issue.

TIA,
