For the first one

SELECT name FROM sysobjects WHERE id = 324208951

Of course, if there's any metadata damage, the table may not be identifiable.

For the second one (Data row (1:2569152:49) identified by (RID = (1:2569152:49) ) ), the second of the numbers is the page no. Use DBCC page to examine the header.

DBCC TRACEON(3604)

DBCC PAGE(<database id>,1,2569152)

DBCC TRACEOFF(3604)

There should be an objectid in the header that you can then look up to sysobjects
