Thanks for the kind words.
1. Yes-once you buy the pack you can drop the sounds into any non-commercial or commercial game, unlimited projects, no extra fees.
2. You may do minimal editing that's necessary for implementation (volume, fade, loop points, file-type conversion) but no creation of new derivative works or redistribution of the sounds outside your own games is permitted.
Don't hesitate to ask if I can help you with anything else.
