A: I suggest "Introductory Functional Analysis With Applications" By "Erwin Kreyszig". Its 1st Chapter gives a very nice introduction to Metric Spaces... Good Luck
A: I suggest Topology of Metric Spaces by s. Kumaresan. 
In the preface:

The aim is to give a very streamlined development of a course in metric space topology emphasizing only the most useful concepts, concrete 
  spaces and geometric ideas. To encourage the geometric thinking, I have 
  chosen large number of examples which allow us to draw pictures and 
  develop our intuition and draw conclusions, generate ideas for proofs. 
  To this end, the book boasts of a lot of pictures. A secondary aim is 
  to treat this as a preparatory ground for a general topology course and 
  arm the reader with a repertory of examples.
