Icon2 Need help with Idler pulley, tensioner and belt replacement

Welp, looks like my 2001 2.3L Auto w/AC has some wearing of the serpentine belt because I am starting to see cracks.. I'd rather replace it now than later.

I believe I found the correct parts according to Gates:

Serpentine; W/A.C.
Automotive V-Ribbed Belt (Standard) K060828

Tensioner Assy.
Belt Drive Tensioner 38155

Am I correct in saying that if I get a new tensioner assembly that I do NOT need to get a seperate tensioner pulley because it's attached.... as opposed to replacing JUST the pulley on the stock tensioner right?

Lastly I can't seem to find the idler pulley?

Rock Auto has three different ones:

DORMAN Part # 419604 {Click Info Link for Alternate/OEM Part Numbers12559325, 12569301, 12580772, 12580774, 2N1Z8678BD, 5R3Z6B209BA, 97221943, F83Z6C348AA, F8CZ6C348AA, XF2Z6B209AA, YS4Z6A228AA} O.D.: 69; Width (mm); 23; Material: Plastic; Type: Ribbed

DAYCO Part # 89006 Drive Belt Idler Pulley; 90mm x 17mm Flat Steel, 30mm wide

GOODYEAR Part # 49001 Idler Pulley - Smooth; Belt Type: 6 rib Poly-V, Smooth; Non-Flanged; Steel; Pully Width: 30.1mm; Bearing ID: 17mm; Bearing OD: 90mm
Accessory Drive Idler Assembly; W/ AC; Smooth Pulley

I guess I should get teh Goodyear one since it's metal but have no clue on the size... as all three of these are different??? I am leading towards the goodyear because it says w/AC so I guess that would work right?

Just wanted to make sure there was nothing else to replace when doing the serpentine belt.. IE::: This is not going to mess up timing or anything like that?

Undo tension, remove belt, remove idler pulley. tensioner, replace with new then put new belt on according to what the little diagram shows in the engine compartment... right?

figured I'd update.

Replacing my serpentine belt tonight along with the automatic tensioner and probably the AC since I have a new compressor sitting here. The stock belt looks old and is cracked, very hard.. new one is nice and flexible. Stock tensioner seemed to be fine honestly... but it's old and figured it's a cheap thing to replace. The pulley on the tensioner however is making a squealing noise so I bet the bearings are shot on it.

I ordered an idler pulley but it doesn't appear at all that this goes anywhere near the engine. I have the tensioner, alternator, ac, ps, and water pump and crank pulley... NO idler pulley... unless this pulley was supposed to replace the stock pulley on the tensioner...

Hope this helps someone so they dont buy parts that aren't needed.
