100k Miles - Best proactive maintenance?

Hi everyone - I'm new to the forum! Joined to ask the collective wisdom here on what would be the best thing I could do for my baby now that he's hitting 100k miles. I plan on taking my tax return and doing as much preventative and proactive maintenance I can for him. I want him to last another 100k! I have listed below the services/parts in order that I'm going to try and get done... I just found it googling articles. I'm not all that learned in car maintenance so all advice is appreciated!

Is there anything that's more critical at this point in it's lifecycle that I don't have listed below? For FJs specifically, is there something that wears out faster which should be replaced? Thank you so much for your help!

Details:

• 2007
• 100k miles
• 2-WD (sad, I know)
• no performance mods, just vanilla
• I've named him 'Otis'

Use:

• frequently on rough road, mild off-roading
• in harsh winter climate
• also take it on extended road trips
• is currently making a grinding noise when in a left turn at slow speeds

Maintenance Considering (in this order):

1. replace timing belt
2. flush cooling system
3. all fluids: transmission, power steering, brake,
4. new spark plugs
5. new battery
6. compression test - replace hoses, clamps
7. replace shocks / struts
8. clean exhaust system
