I've seen people telling good things about Chris Pines' book:
http://pine.fm/LearnToProgram/
although I haven't read it.

Your program looks fine. The only comments are idiomatic stuff:

In Ruby the convention is to use snake_case. Also names that start
with an uppercase letter are constants, so I'd do:

first_name = gets.chomp # also, don't be afraid to have longer
variable names if they are clearer

> puts 'What is your middle name?'
> Mname = gets.chomp

middle_name = gets.chomp

last_name = gets.chomp

puts #no need to pass an empty string


> puts 'What is your age?'
> Age = gets.chomp

age = gets.chomp

> puts ''

puts

> puts 'What is your favourite number?'
> Fnum = gets.chomp

favourite_number = gets.chomp

Also, my preference is to transform strings into integers the earliest
possible if the concept is really a number so, I'd do:

age = gets.chomp.to_i # or Integer(gets.chomp) for more strict tranformation
favourite_number = gets.chomp.to_i

> puts ' '

puts

String interpolation is preferred to concatenation (less objects to create):

puts "This is your information..."
puts "You are #{first_name} #{middle_name} #{last_name}."
puts "Your age is #{age}."
puts "And your favourite number is #{favourite_number}"

> C = Fnum.to_i
> A = Age.to_i

not needed anymore

> NFnum = C + A

new_favourite_number = favourite_number + age

> puts 'Maybe, your favourite number should be ' +NFnum+ '.'

puts "Maybe, your favourite number should be #{new_favourite_number}"

which by the way removes the problem you were having, since string
interpolation calls to_s automatically.

Jesus.
