1. No such thing yet, completion is bare-bone at the moment, but it's open to extension.
2. Show the guile snippet or pseude code please, it can help me understand better what you mean.
3. At the momnet there are no debugging capabilities except printing a backtrace and exception.
If you have any ideas on how to implement particular functionality (the code or just the overall idea) drop a message on rde-discuss or rde-devel:

2. For example call geiser-doc-symbol-at-point and try to find the string-match function. It requires (ice-9 regex) to already be loaded.
I was not familiar with the sourcehut platform, I would be happy to collaborate (I need to learn this email workflow)
I have thought about using geiser-eval--send to eval some modules in a separate buffer, and also to somehow extract the list of symbols out of the modules, a hacky solution for points 1 and 2. I will explore this.
