In the abscence of a Bryce manual, I recommend acquiring “Real World Bryce 4” by Susan Kitchens and Victor Gavenda (ISBN 0-201-35438-1). Being three versions behind, it won’t cover the latest features - but it will provide you with comprehensive guidance for these basic questions. It also covers a lot of creative ways of working with Bryce that are still applicable today.
Since you’ve stated that money is tight for you, I’ve checked for used copies on Amazon and very good condition examples go for as little as $1.24 plus $3.99 shipping.
Apart from Bryce itself, this is likely to be your best Bryce bargain.
