It appears that Googlebot Mobile will look for mobile redirects from the desktop site, but still use the SEO from the desktop site.

Is the above statement correct? I've read that its better to have different SEO titles & descriptions for mobile sites as users search differently on mobile devices.

I've also read it's good to link build, keep text content on mobile sites etc to get the mobile site to rank.

If I choose to not have titles & descriptions on my mobile site will Google just rank our desktop version & then redirect a user on a mobile device to our mobile site or should I be adding in titles & descriptions into the mobile site?

Thanks so much for any help!

Most of this is speculation based on the features and changes Google has been pushing out.  Taking into account the mobile initiatives Google has been implementing like GoMo, the mobile Googlebot and the different SERP's for mobile users from desktop users, I would have to say that it is important to optimize your mobile version as well. If you have a responsive design then your meta information may remain the same unless you simply serve up a different menu all together.

Your CTR's are probably going to be different as well as your linking architecture.   Just make everything user friendly by considering the user's context and you should do awesome no matter the changes Google puts in place.

Interesting question, thank you.

I would say same URL same HTML.  Or  you can try  another approach by  having completely different  URLs and HTML for mobile site. You can manipulate your title and meta to have special message suitable for mobile users, it will not directly affect your ranking, but it might affect your CTR.

I hope it helps.
