Clockwise is normal direction, i don't think it really makes any difference.
You do not need to use the mark on the flywheel/pressure plate. Use the marks on the timing belt end.
I would recommend changing the tensioner as well.
You can do the job without any special tools, however it is easier to get the special tool to turn the tensioner.
Only other tricky bit is getting the crankshaft and water pump pulleys off, they are allen keys so make sure the socket is in flush.
Get someone to give you a hand if you can, and take your time! rushed job means trashed engine.
Pay attention to the timing marks, make sure they stay lined up when tensioning. Check them, check them , double check them etc...
