I disagree. You shouldn't even be ABLE to lug it in first gear pulling out.
You should be able to IDLE and let the clutch fully out (slowly enough that it doesn't stall) then press the gas hard and accelerate. If it clatters when you do that, it's PINGING and needs fixed. If it does that AND you have larger than stock tires, you are lugging it and should consider re-gearing. You should be able to IDLE up small hills in first gear and if you hit the gas it should accelerate with no odd noises.
If it won't do that, you may need plugs, wires, IAC, Intake cleaning, engine decarboned (Seafoam), EGR problem, etc. If it's really just a clutch-related noise, I wouldn't worry about it until the clutch goes bad.
Lastly, CHECK your transmission and Transfer case ATF fluid levels.
Many many many MO5D trannies die from lack of fluid.
