Credit cards are also useful when paying for expensive items such as....er, Vegas holidays.
A few years back I booked flights to Vegas on MaxJet, whose selling point was that all seats on the plane were business class. Cost was around £800 for return to Vegas from Luton IIRC - so double the price of economy at the time but way cheaper than regular business.
Sadly they went bust a few days before Christmas and I was due to fly on NYE. Thankfully had paid on credit card so got the money back from Barclays and booked some economy flights on Virgin to save the trip.
Sadly there's (almost) no escaping the resort fee these days and various websites have lists of them all and what they include.
As for the drive to LA, you've been correctly advised it's about 4.5hrs, I did it on my first trip to Vegas many years ago.
You might also want to check out the hotel review thread in this forum as there is some good advice on how incidental costs can add up (taxis, drinks, room service etc
(Edit: It's post #1830 by LuckyTxGuy and is currently on the last page)
Walking the strip is a good idea - it won't be warm in November, even to a Scotsman, but you will save on fares, get some exercise, see the sights and also be able to do a "poker room crawl" and play in as many of the different casinos as you want. Collecting $1 chips from each is optional but a nice cheap souvenir.
Hope this helps (drop me a PM if you need more info)
