Re-arranging incoming linking today.

Still lots of questions.

[Saman]

What is a better way to arrange incoming links to my site today to improve my Google rankings?

Should i de optimize existing links filling them with some trash e.g. domain names, project names etc?

Should i use "Google synonims" in some proportiontolink to my site?

What are the basic AfterFlorida instructions of building links?

Thanks.
