Combining 2 Onedit functions ib 1 script - scripting

Question

I have 2 onEdit scripts as detailed below that conflict. I need to somehow combine the two scrpits in to one. The fist script autosorts when column 9 in Worksheet1 is edited.
Question 1: How to make it run if i need the same function aswell but column 11 in Worksheet2?
The other script inserts a row onEdit, however it does this on all worksheets.
Question 2: How to restrict it to run when a certain cell is adited ie:Q2 on Worksheets 1 & 2?
Question 3: How to combine both scrips into 1 script?
I am a complete novice at script writing so please make you ansers as simple as possible, thanks
Scripts I have that work separately:
Script 1 AutoSort
function onEdit(event) {
var sheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
if(sheet.getName()=='Worksheet1') {
var editedCell = sheet.getActiveCell();
var columnToSortBy = 9;
var tableRange = "a3:Q999";
if(editedCell.getColumn() == columnToSortBy) {
var range = sheet.getRange(tableRange);
range.sort({column: 9, ascending: false});
Browser.msgBox("sort done");
}
}
}
Script 2 InsertRow
var ss = SpreadsheetApp.getActive();
function onEdit() {
var firstRow = 3;
var sh = ss.getActiveSheet();
var lCol = sh.getLastColumn();
var range = sh.getRange(firstRow, 3, 1, lCol);
var formulas = range.getFormulas();
sh.insertRowsAfter(1, 1);
newRange = sh.getRange(firstRow, 3, 1, lCol);
newRange.setFormulas(formulas);
}

Answer 1

I usually make one onEdit function, which will call some other functions one after another:
function onEdit(event) {
myFunction1(event);
myFunction2();
}
function myFunction1(event) {
// do something
}
function myFunction2() {
// do something else
}
