How easy is it to replace a trigger pack?

I'm trying to replace a trigger pack on a CA-94. I would have posted this at HKpro, but I'm still in line to get my account activated...?

That's the complete trigger pack, how easy would it be to replace this?

Very easy.

Rotate the safety, remove, and pull out the trigger pack.

is replacing the trigger pack really necessary in a CA-94? I've heard that parts of the trigger group is unreliable?

Do you have a CA-94? If so, have you even shot it yet?

If you answered "No" to either of those questions you should not be considering a change of the trigger pack. You should own the gun and shoot it before changing any parts. In some cases a parts switch is not even required. The most common needing changing I've noticed is the extractor, and it's spring. If something in the trigger pack needs replacement it is usually the ejection lever.
Food for thought... You've got to consider 922r ramifications when dealing with the trigger pack. If you swap in a 100% semi-auto surplus pack you may be in violation of 922r rules. It is best to just replace what may not be functioning in the pack for the sake of $$$. HTS Combos for the HK trigger pack would run you about $75-$90 alone.

Piece of cake. Follow BStrong's instructions.
