2004 V6 3.9

Just reached over 100,000. I'm going to replace the inner belt , but what else is a good idea to change while I'm in there? I'm already going to order all new idler pulleys from billetflow for the outer, both new tensioners, replace the powersteering pump. I know there's 3 idlers in the inner too but can find much information, size? Do most people replace them with just anotherstock idler or aftermarket?

Thanks
