Attributes Queries

[mattclements]

Hello all,
I am working on a Site that will be using Attributes as follows:

Size:
X-Small
Small
Medium
Large
X-Large

We will then add this attribute to a number of products and want to know whether it is possible to disable certain attributes in the created list? So for example a Fireman Outfit may only come in Small, Medium and Large, where another outfit may come in every available size.



Also on another matter, is it possible to set the product code (sort order) and price based on the product rather than just the attribute - for example:

Fireman Outfit:
X-Small: 001: £10
Small: 002: £10
Medium: 003: £10
Large: 004: £15

Policeman Outfit:
X-Small: 005: £10
Small: 005: £12
Medium: 005: £15
Large: 005: £20
X-Large: 005: £25

Also how well are Zencart Attributes indexed? So if I searched for Small Fireman Outfit would this be in our Sitemap (Generated by Sitemap XML) or will it just have the root product?

Thank you in advance.

Regards,
Matt
