looks all DIY possible, depending on your tools and ability, and how much you want to get into it. The suspension arms and hoses I would think is relatively "easy".

It looks like a lot more work than honda, but maybe not to bad. ? (I'm a replace-the-axle instead of a repair-the-boot kind of person.)
The last visit they replaced the PS hoses for leaking (under warranty.) Really, they were not leaking, just damp he said. If yours is similar, maybe you don't really need to replace.
