I saw some at the dollar store last week!  The best dollar store in Canada is Dollarama.  Do you have that chain near you?

For all my little bits and bobs I use shoe-box sized plastic boxes.  Clear with coloured lids.  I have them sorted into categories like one for small tools, one for silk flowers, 1 for beads, 1 for wood shapes, 1 for buttons and charms... They stack nicely on the shelf in my craft room closet.  I have about 15 of them!  They only cost a buck or 2 at Staples or a department store.  Staples also sells bags of ziplock bags in small sizes from 4" x 6" down to 1" x 2".  Great for sorting stuff inside the shoeboxes.

Paper should really be stored flat.  I just found a cube unit at Canadian Tire.  It has nine cubes, each cube is 14" d, w, & h.  Luckily, this one came with dividers and drawers and cupboard doors so I can store glue and paint in the cupboard ones.  The dividers let me divide each cube into narrower sections either horizontally or vertically.  Great for paper or magazines.  I found it on sale and paid less than $150 for it.  It also fits in the closet and I can store my bigger papers flat on top of it. 

Almost forgot... I have an old travel trunk of my grandparents, I cleaned it up inside and use it for fabric and yarn.  I have seen several around in second hand stores lately for as low as $30.

Finally, my room is tidy and I can find what I need when I need it!  Now for the rest of my life...

I agree - just relax and go for it.  I struggle with the same problem.  One thing that has helped me is setting a time limit.  I would normally spend days on sketching a portrait.  So I looked for interesting faces in magazines and Karsh books picked up at 2nd hand stores.  I would pick a subject and say - I am going to draw this in 20 minutes.

If you are working in a medium that needs to dry between layers, limit your time spent at each session as well as your over all time.  Also, you must make time for your art every day!  The more time you put in, the more relaxed you will become and your style will evolve naturally.  Have fun!

Be creative with your location.  Since you have to do an indoor shoot, do you know anyone who could get you in after hours to some interesting location like a theatre or restaurant or boutique?  Somewhere that has luxurious decor, where you wouldn't normally expect to see a scantily clad woman.

You could paint over it.  Make sure you clean it well and then gesso it first to give yourself a fresh ground to start on.

be careful what images you use out of magazines.  All creative material is automatically covered by copyright.

It's a great idea, but how about using images of your own and adding materials and natural objects to your scan?

What about Podge?

or just diluted white glue.

Decide on your layout in advance.  You could add a title, photo, labels, etc. for colour or interest.  You could also mat some of them on thin coloured paper for a bit of colour, to highlight ones of particular interest.  just cut the coloured paper about a 1/4 inch bigger than your receipt so you have a tiny strip of colour showing all the way around.
Spread a thin layer of glue/podge on your page.
Transfer your layout to the podged page.
Cover with another thin layer.
Leave to dry.
