[Plugin: Yet Another Related Posts Plugin] code to locate related post

Hi,
I just installed this plugin and I have to problems:
1. Right after the title of the post comes out numbers between brackets I don’t know how to take out like : title title title (3.1190) —- how to solve this?
2. I am not a an expert in php and the explanations to manually use the plugin are not very clear to me. I would like the recent posts to appear after the tags, I tried adding <? related_posts() ?> after the tags on the categories code, but i just didn’t understand how to configure it.
Please help with this.

An idea: Isn’t possible to add to your setting options a final part where after configurating all the options you get the php code as you wanted.
