R&R Oil Pump?

[Blue94]

I am putting together an order from SubaruParts.com and wanted to confirm a couple of things. I am replacing my front main seal and the little o-ring on the back of the pump. I am just wondering if I need to buy a new oil pump while I'm in there or are they fairly stout? I have 155k on the odometer. This is what I have so far:

2 14075AA021 Gskt Intake Collector $6.72 $13.44
1 806733030 Oil Seal $6.53 $6.53
1 806919050 O-ring $2.32 $2.33
2 24236AA001 Clip $3.28 $6.56
1 22633AA080 Throttle Sensor Asy $226.28 $226.28

I was thinking of doing the cam seals and caps but thought I'd open it up to see if they were leaking before ordering. As far as the other parts, I am pulling my intake to get to the PVC so I thought I'd order new gaskets. ( I stripped the PCV trying to get it out from the top) And lately at random the car cranks considerably more than usual before starting. I have read that it is probably the TPS though before I order I am going to test it with a multi meter. They must ship this little bugger special as the shipping jumped $20 when I added it.

Am I missing anything?
