What got me thinking is I'm finding oil low and coolant tank empty. Poured in some distilled water (to the coolant tank of course - I'm a piggy not a dummy!

) to tide it over. I'm also planning a switch to Toyota Red. I also find one timing belt cover bolts being hand loose.
I found the timing belt DIY so I'm not looking for the how, but what can/should/must I do along with it with 3 days of the labour day weekend and the next 4 days to get parts.
What has been mentioned to be done along with timing belt:
water pump
oil pump O-ring
front main seal
front camshaft seal
What's usually done as well at 96k KM
ATF/diff drain/fill (I did this once before)
spark plugs
rotate tires
whatever else I can find from Toyota's maintenance menu
Besides oil change and coolant change which will need to be done, over all these things that can be done and the time I'll have available, can I try doing all of these or should I pick my battle assuming I'll finish the job in double the time it takes a shop? What are my priorities?
