printing multipage booklet

[tinminer]

i was using the trial but it has expired before I got to test everything- duh....... not your fault

this did leave me some questions on how to print the booklets.
if I want to print a booklet with multipages
Q1 how many pages can I construct in a booklet .

Q2 if I have a text file and paste into the booklet will it flow over pages to make a multipage booklet.

Q3.if pages are in order in the booklet template 1,2,3,4,5,6 if i print a book (probably 3 sheets?)then fold them
I would get pages in order of 1,3,5,6,4,2 when folded with text on the inside OR 2,4,6,5,3,1 folded with text to the outside , with blank sheets in between for where the backs are.
SO does the booklet have to be constructed with the page interlaced by me or does it change the page order to print so that when they are assembled and folded they come out in order?

My printer is capable of printing both sides, so if it printed interlaced they would fold and be all in layout order.
ie.
sheet1 front Blank:P1
sheet 1 back P2:blank
sheet2 front P6:P3
sheet2 back P4:P5
assembled as P1,P2,P3,P4,P5,P6,blank,blank
