Sorry, I don't really have time to play around with templates atm to see how to do the second part. I guess you could try
Styles & Templates > Style Manager > Edit Templates > Threadbit Templates > threadbit
FIND:
Code:
$thread[threadtitle]</a>
AFTER ADD:
Code:
- $thread[lastpostdate]
that wouldn't remove it from the Last Post column tho...
while in that template you could remove $thread[lastpostdate] and that
should remove it from the last post column... this is untested, make sure you save a copy of your threadbit template incase it doesn't work out
