Footcite that changes format on second citation

Question

I'm writing a report for the university. They're being very specific about specifying formatting for citation. Although I suspect the mentor won't be very strict, I'm still interested in having as close output from LaTeX as possible. I'm an utter newbie with LaTeX, so I'm learning as I go.

Having picked up a template from another Croatian university that has a very similar format, I've began writing my text and customizing the template as I go. The issue I ran into is with citations.

Here are the (translated) instructions on citing:

Citing: On every page, place reference into a footnote. See appendix for information on format. Literature: At the end; list authors alphabetically.

And:

Note: For second and other citations of the same bibliographical unit, you should list the following: First and last name of the author, in parenthesis a numerical identifier of the footnote where it's first listed, number of page where it's first listed.

So far, I switched from bibtex to biblatex and biber in order to make use of \footcite. I've played with some defaults (style=numeric, …), but I feel that as a newbie it'd take me a long, long time to figure out how to get this exact behavior.

How would I go about forcing full bibliography entry to appear in the first reference to an entry in a \footcite, then having subsequent entries display author name, first footnote's ID and first footnote's page number, while at the same time having full entry appear in the Literature section?

\usepackage[style=verbose-note,pageref]{biblatex} does most of what you want. Here's how to add first names to follow-up citations (and replace the comma with parentheses):

\documentclass{article}

\usepackage[style=verbose-note,pageref]{biblatex}

\DeclareNameAlias{labelname}{first-last}

\usepackage{xpatch}
\xpatchbibmacro{footcite:note}{%
  \setunit*{\addcomma\space}%
  \printtext%
}{%
  \setunit*{\addspace}%
  \printtext[parens]%
}{}{}
\xapptobibmacro{footcite:note}{\nopunct}{}{}% optional

\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}
@misc{A01,
  author = {Author, A.},
  year = {2001},
  title = {Alpha},
}
\end{filecontents}

\addbibresource{\jobname.bib}

\begin{document}

Some text \autocite{A01}.

\clearpage

\null\vfill% just for the example

Some more text \autocite{A01}.

\printbibliography

\end{document}
