Hi,
1. IDs in links can be turned off by setting the backend parameter "Remove products and categories id in URLs" to "yes" (under "SEF url options").
Not entirely sure if that'll work for you, but maybe worth a try.
2. If you're using a filter module,
NoNumber's "Advanced Module Manager"
(Pro version only), gives you the required extra control on which HikaShop pages modules should appear and where not.
However, there's been at least one other thread here recently questioning how much sense it makes to display filters on a product page, and if I remember correctly, it's being considered to make it optional in future versions?
Hope it helps.
