So, here's the answer.
To create dot-to-dot picture you need to trace it with the Pen tool. As the result you should have one not closed path. Copy it to another layer.
Answer 1.
Select the copy of the path and go Select > Object > Direction Handles and press Del. Then go to Effects > Convert to Shape > Ellipse. Create an elipse with diameter about 0.01 of any unit. Then set stroke to 1pt. Thats how you recieve the array of dots but ypu still need to label them with numbers.
Copy all of those dots to another level. Then use this script

to replace the dots with the text label you've created before.
Answer 2.
All you have to do now is to manualy adjust the text objects and fill them with apropriate numbers.
