Basic pdf list with pdf icons

Hello, this looks like a great plugin and should be able to do what I want, but I cant seem to get it working properly. Ive trawled through the support threads but still have issues. By the way, it seems the support you offer is outstanding, so thank you in advance!

I plan to have lots of pdf files and will assign them various Att.Categories, such as ‘product-manuals-stereos’ and ‘product-manuals-speakers’ etc. I want these to be listed, with the standard pdf icon, with the pdf doc title to the right hand side of the icon.

Ive tried the short code below, found from another support thread and amended to display my att. category ‘product-manuals-stereos’ but have the following issues:

1) there is no caption/title visible
2) the layout/spacing of the pdf icons is very far apart and looks cascaded, i.e. the 2nd pdf is slightly lower than the 1st
3) id like to update the icon to be the standard red/colour pdf icon (looks nicer!)

[mla_gallery size=icon post_mime_type=application/pdf columns=2 link=file post_parent=all attachment_category=’product-manuals-stereos’]

I hope you can help, or point me in the right direction.
Thanks
