A new player looking for help

[Jask]

Thank you all for your great help.

Welcome to the Raven fold! From Monster Hunter to Armored Core... you truly are a sucker for punishment.

Don't forget God Hand, Ouendan and Chaos Legion. Gaming and romance seem to be my masochism lines.

I've a couple more questions:

• I see two stats on the radiator: Cooling and Forced Cooling. What is the difference between the two?
  
• Is the AI Capacity Stat on the head unit just how well the AI will run? Useless if I play manual?
  
• The controls say Triangle is for for switching between right arm and right shoulder. What about the left side?
  
• How do different radars function? How necessary are the various features and radars in general?

One last thing. There are so many different parts, I'm a little lost on which to pick first. Any suggestions on order of part application?
