custom statistics from gallery to Drupal + ideas

May be you'll find this information useful for the further development of gallery module, but I'm writing here to ask how I can do such things in Drupal 4.6.4 and kiz's gallery.module v.1.1. In fact, I just need php-snippet to be included in some php-code-style drupal page or may be some gallery.module hacks. I'm not the programmer, but I will need to have it sooner or later, better sooner... in any way. May be you help me. ;=)

1/
I need a custom page (or even hand-made block) in Drupal to show statistics:
a. how many pictures are in gallery in total
b. how many pictures are in gallery with SpecificItemId (some albums and all it's subitems)
how?

2/
Users navigation menu must have "my albums" forwarding to user Ablums (gallery's Users Albums module).
First time, it's usually /gallery?g2_controller=useralbum.UserAlbum, but after album is creates it must (?) be something like /gallery/users/user_name. I created this menu manually, but it's wrong (?) to call everytime user albums by the first g2_controller and also I can't easility hide this menu from guests who can't have their albums
need module hack?

3/
User profile page must have the same link "my albums", probably with shorl list of his albums inside. In general, with all statistics considering his albums - number of pictures, albums e.t.c.
need module hack?

-------------------------no so important, but as a idea
4/
If Quota module is active, user shoud have how much space he uses. I didn't see this function ever in Gallery. It would be better to show it (disk usage, quota and space left) on the user's profile page.

no more ideas. =) If you could make all this in super-enchanced module for 4.6 I'll try to use it. If it will be only for 4.7 I'm sure that I will be able to upgrade, so. just let me know on which of first 3 points I can awating some guide how to make it all possibile. thx u all.
