Need to install new software in my T60 & my R52

[NS]

I need some suggestions from everyone

I need to install a new software in my T60 & R52 and i saw many available softwares in the market. Please help me decide on one suitable software.

I need a chinese notepad software. I found NJ Star and some other softwares. Sounds great but i don't know whether it is easy to use. Need to type a few chinese words. I need those types of software which i can just type in the hanyu pinyin and later choose the chinese word in a small little browser.

Main purpose: need it for my school project as i am currently doing a business proposal with China people and they used all sorts of traditional chinese characters in their reports and make me see till my eyes roll... If i don't read what they wrote carefully, they will swindle my cash. So i need help on this software.

I don't care how much it costs but just give me some suggestions which are the best chinese traditional characters software.

Thank you.
