1: Create a new file in NameX/css/custom/custom_edits.css. Then add the following:
#messageindex #topic_container .board_stats p,
#messageindex #topic_container .board_stats p strong {
font-size: 11px;
}
2: You can change this through the default settings of the forum. Go to Admin > Forum > Attachments and Avatars > Avatar Settings. In there you'll notice four settings related to width and height. Adjust the values to something smaller.

3: I'm not sure what you are trying to accomplish. You could hide more things from the poster. For example, in the file you created for the first image, add the following:
#forumposts .poster ul.user_info li.blurb,
#forumposts .poster ul.user_info li.im_icons,
#forumposts .poster ul.user_info li.profile,
#forumposts .poster ul.user_info li.title {
display: none;
}

Yo can add your own CSS to overwrite styles.
Create a file in NameX/css/custom/custom_edits.css

You can also tweak responsive.css for some mobile changes, or include the media queries in the new file.

De momento no estoy disponible.
Quizás en el futuro.

Not available at this time, it's up to the author to update it.

I will try to have one or two later this year. Potentially one of them might be a rework of a previously available theme.

Thanks.
You should have access to all the boards now.
If you have any issues just open a topic in the support board for the theme 

There are currently no plans to update the theme.
Perhaps in the future.

I'll have a look when I get some free time, hopefully soon.

What would the 'add here' part mean?
Regarding the search, it could introduce a UX problem for your users depending on the size of their screen, they would most likely only take advantage of such change in a large screen.

De momento no se ha trabajado en una traducción, espero que más adelante lo pueda hacer.

Find/use a compatible theme.
This theme is unlikely to come back updated.

No, it's no longer offered at this time.
