As a Live Helper, it's our job to help people with questions about Second Life.
This does not mean we have to do work for other people. Often times, our job is not to lay out the help for someone, but to point that person to where they need to go.
Now, while it's voluntary to go above and beyond and hold hands through an issue, we do have a mentor program and forum in place whose task is to do more of the guidance and teaching specific "how-to"s of building, scripting, etc.
Here's some examples with some subtle differences on how I would handle situations, with a couple variations.
Scripting:
Q: What command makes an object move?
A: llSetPos() or llSetPrimitiveParams().
A: I'm not sure, there's no scripting expert on Live Help right now, but here's a link to the scripting WIKI and to the scripting tips forum.
Q: "How do I make a sliding door?"
A: Here, I have a simple sliding script for you.
or
A: Here's a link to a thread in the SL scripting library forums where you can get a script.
NOT: Let me explain step by step how to script this.
Q: I found a bug in llSomeCommandThatYouDontKnow()
A: I'm a scripter. Let me try this out and submit a bug report.
A: I'm not a scripting expert, but let me ask a friend who might have a better idea ...
A: I'm sorry, there's no scripting expert available on Live Help right now. I would recommend posting your question in the scripting tips forum. Here's the link. Also, if you can find a simple reproduction, please feel free to file a bug report and detail the problem and how to reproduce.

Textures:
Q: How do I upload a texture?
A: File -> Upload Texture. If you're uploading an alpha texture, it needs to be TGA 32 bit.

A: What file type? Is it transparent? (etc)
Q: How do I make a cool texture for a dress?
A: Here's a link for the templates for clothing. Also, here's a link to the building forum for SL.

A: (explain a few ways to manipulate a prim)
Q: I need to build a house help!
A: Here's a link to the building forum for SL. You may want to check out advise from other players there. There's a lot of resources already online to help you out.
