Direction of tread isn't too important unless you're using really chunky MTB tyres. If you're being perfectionist about it then yes arrows of tread pointing forwards. Some will tell you its to channel water through in wet conditions.
Sometimes putting tubes on a warm radiator before fitting and leaving the rim outside on the cold can help fit tight tyres. Really depends on the rim though and it's age too.
Making sure the tyre is really well seated into the rim on the part you've got on does make a big difference.
Even getting yourself a couple of extra mm of play using the above when getting a tight tyre on can be the difference between getting it on and not.
I find swearing loudly can also sometimes scare the tyre into behaving :)
