How to optimize the site according to analysis response?

Question

I recently blogged for my wife, https://danielafolle.com.br/ which I am now working to optimize the response time of the site.

I’m using the Pagespeed Insights Google to base if I’m progressing on optimization.

At the end of the analysis, it generates a report stating which points can be improved to optimize the site.

When analyzing the Website I get 4 answers that I can’t optimize.

Eliminar JavaScript e CSS de bloqueio de renderização no conteúdo
acima da borda; 
Aproveitar cache do navegador;
Ativar compactação;
Otimizar imagens.

The first and last problem is fine, because the first has to do with the plugin Self-loathing Wordpress that inserts the CSS on the page and the latter are the images that are related to Adsense.

It turns out that the compression and reuse of browser cache are active in the . htacess of Wordpress.

Deflate - Gzip

<IfModule mod_deflate.c>
AddOutputFilterByType DEFLATE text/plain
AddOutputFilterByType DEFLATE text/xml
AddOutputFilterByType DEFLATE application/xhtml+xml
AddOutputFilterByType DEFLATE text/css
AddOutputFilterByType DEFLATE application/xml
AddOutputFilterByType DEFLATE image/svg+xml
AddOutputFilterByType DEFLATE application/rss+xml

AddOutputFilterByType DEFLATE application/x-httpd-php
AddOutputFilterByType DEFLATE application/x-httpd-fastphp
AddOutputFilterByType DEFLATE application/x-httpd-eruby
AddOutputFilterByType DEFLATE text/html

SetOutputFilter DEFLATE

BrowserMatch ^Mozilla/4 gzip-only-text/html

BrowserMatch ^Mozilla/4.0[678] no-gzip

BrowserMatch ^HMSI[E] !no-gzip !gzip-only-text/html

SetEnvIfNoCase Request_URI .(?:gif|jpe?g|png)$ no-gzip dont-vary
</IfModule>

And the use of cache:

<IfModule mod_headers.c>
Header unset ETag
</IfModule>
 FileETag None

It may be that I missed some parameter in my . htacess configuration?
