Dear Arm,
I agree with funksen - you do not have to be a mega scripter to administer - especially AIX - systems - we have smitty !!! - but you should understand enough about scripting to modify some very useful scripts for your needs.
I am myself AIX SA since about 4 years in a large company - and I hate scripting ! But sometimes you cannot get around.
Anyway - if you're working in the projects area mainly building AIX systems, you should be able to survive with just basic shell scripting skills
Take care
