Any useful tools?

Hi, im new to internet marketing and seo. I have lots of free time and i am committed to put in the hours to become successful. Please could you inform me of some programs which you would say are very useful to have. I do not mind paying for these tools if they help me. I currently have xrumer, scrapebox and market samurai but is there a tool which can do some really good analysis of keywords for me and give me good information on the keywords? Market samurai does this but im looking for a little bit more information.

Thanks in advance

I know SEnuke has a niche keyword finder

To be honest, the price just doesnt seem justifiable, maybe one day i will purchase it.

Lol you buy xrumer and you say that senuke is expensive?

lol true, well i think xrumer is worth alot more than its current price. But senuke works out to be more expensive than xrumer. Maybe one day i will invest in it, but for the time being its definately a no no.
