Ideal .htaccess file for GS. Help please

[spring]

I found this by googling. It's for wordpress but I made some changes to adopt for GS. I'm not sure if this is the "best" so I'd appreciate any help. My installation is default GS template.

Please comment what lines are needed, what's not? Are there missing entries to improve security?
