not sure how much I can help, but these are what I use on my girls
1. we get our hair bands from petedge.com the heavy duty type, works great on Dolly and very good price
2. we got our id tags from ebay, shown in the picture attached, we actually saw them from a local pet boutique, I just fell in love with how sturdy and fashionable they looked, they are made of stainless steel, but they were quite expensive, so I searched on the web and found a canadian seller that sells them for really cheap (I think $4 a piece with engraving included). and the girls' been wearing them for 3 years and they are great. (if you search for dog id tags in ebay this seller should show up)
3. bull sticks we get them from a vendor on here her username is AMD her website is 
www.westbrookdog.com, hers don't smell as much and def. cheaper than anywhere else
4. bush, we use the Chris chistensen fusion pin brush, there is one option for toy dogs. it's static free and works great on Dolly's hair and she's got semi-long hair (used to have a full coat). we get most of our grooming products from 
Show Dog Grooming Supplies, Andis Dog Clippers, Oster Dog Clippers, Bio-groom , it should be listed under Chris Christensen products
5. detangler, we've tried a lot of things, while nothing really worked magic (the only trick is to brush often), I like Chris Christensen ice on ice the best, its non greasy with added sun protection, it can be used for just about everything. I got it from the same place as 4.
