Need help prioritizing repair work needed on my Nissan 2006 Murano.

The missing fasteners for the various shields should be replaced otherwise they may come off, some are pricey. The brake fluid should be replaced every 3-5 years per most manufactures now days Original coolant hoses should be good for 10years in most cases, we replace them when we change the radiator Fuel system service is preventive maintenance, adding good quality fuel system cleaner available from parts stores works fine if used say every other tank fuel.
