I'd disagree. This is obvious depending on where you release it. The new guideline does state optimized anchor text and if you are just linking to your homepage, that is fine.
As long as you are not optimizing the anchor text, it would be alright if you just link to your homepage with just the URL.
Title tags may vary. And could be anywhere from ~50 through ~70. It is measured by pixels.

What Tuzzell quoted is true. Subdomains is not for languages. It is mainly for SEO value and structuring of your site.
Subfolder is the way to go.
The rationale is that subfolders will have links from all parts of the site including from the different language section. For subdomains your ranking might fluctuate between different languages.
Subdomains are not used very often except to differentiate a primary domains core business and purpose. If it is usually just language, a subfolder is what everyone normally uses.
