Module development and code questions

This seems like it should be pretty easy but my knowledge of php is so very limited, so here goes...

I have a module that is basically adding one line to the end of blog nodes, which works fine in itself. But I need it to pull a specific profile field from the author of the node.

First, I need to define who the author of the node is, and then take a profile field based on that.

I could just use a nudge in the right direction, since everything I try seems to fail miserably.

Any help would be awsomeness.

I'm trying to develop a tool that will query recent forum posts for specified keywords... and depending on the keyword - will email a specified recipient about the post.

Basically I just need a simple interface to enter a list of keywords and an email address that will receive updates when those keywords are used. I will need the ability to add multiple email addresses (one for each group of keywords) and would like to email a simple message saying something like:

"Your keyword * was used recently on the following page *"

I was told that it would be easier to modify the E-Commerce module in 4.7 where Form API is used. However, it seems to me that not everything can be modified by Forms (yet). Here is an example:

Assume we want the price of the product to not be shown to the user. The price appear by the function theme_node_product in product.module as the following:
