Blog post issues

Hi Sakin,  I have noticed on the upgrade that after the post but before the comment section, there is a line which gives the category information. As I have the breadcrumbs at top, I don't need this at the bottom. How do I suppress this? Also, I would like to have the comment box left justified.  How can i do this?  As well, there is a "comment" tag outside the comment box. This is redundant, how can I remove this? Thanks for your help. - Karin
