Hey Shivun,
I've been using the "SmartSEO" plugin for ~2 years and I love it. I think it cost like 10 bucks.. It simply gives you frontend access to edit meta data when you're logged in as superadmin. Saved me countless hours.
I also just this week installed "JCH Optimize" plugin which decreased load time nicely, a common problem when you run a Joomla site with bells and whistles.. The standard GZip and other plugins that do this would always break some part of my site, but JCH had enough options that when I tweaked em just right I reduced load time by about 30% without breaking anything.
