Brake Fluid flush and Oil change/filter at least.

Then take apart the oil filter element and inspect for metal, plastic and magnetic bits.

New engine air filter and perhaps the cabin air filter as well as they are all likely all original.

Be sure to get the recommended brand/type of oil, you will need 9quarts of it.

Be careful of striping the oil plug as its going into aluminum, so be gentle.

Also, take pictures, we want to admire another Porsche.

As for coolant, you should not DIY unless you have the right tools for changing it out. Its quite common for inexperienced with Boxster folks to incompletely bleed air out of the coolant system and cause further issues.

I would keep an eye on your oil filter for Magnetic bits which may indicate bearing issues but its only 1 in 10 of the single row bearing 986's that will ever have an IMS issue so don't loose any sleep over all the IMS hype. Just be on the lookout for magnetic bits in the oil at regular 5k miles oil changes. A magnetic oil plug is a wise investment to that end.
