I'm replacing a timing belt on a 1997 Honda Civic w/ a 1.6 liter engine also doing the water pump. Ars there any other things that should be done at this time like seals or anything? and can I get specs on how to line up the timing marks please?

The only other thing could the the timing belt tensioner if there is any doubt. Here's the timing marks.

I set the Crank timing mark to 0 ( Top Dead Centre )

Before you remove the Belt.

Use White Paint Pen to mark the belts & sprockets.( Cam gear...Crank gear... Water pump gear)
1 tooth only per gear & belt.( You should have a mark on 1 tooth on the gear & belt).

MARK THE BELT (A =CAMGEAR W = WATER PUMP C = CRANK GEAR )

Loosen tensioner & remove the belt (try not to move/turn any of the sprockets/gears)

IMPORTANT !!!

Count the TEETH on BOTH BELTS. ( MAKE SURE THEY HAVE THE SAME AMOUNT OF TEETH)

Mark the new Belt.COUNT THE TEETH BETWEEN MARKS ( should have the same amount as the old belt). Mark A ... W ...C ...

DOUBLE CHECK THE NUMBER OF TEETH BETWEEN MARKS.

Reverse installation for assembly.

Ensure timing belt marks match up with the correct gear marks....A...W...C
