99 gs rebuilding 420a ??s

hey guys,
I spun a rod bearing I believe so I am going to break down the engine this weekend and rebuild. I am not interested in boosting the hp. I am just looking to rebuild stock or close to and try my best to stay under $600. I seen some rebuild kits on ebay for $375 this is what one of the kits include:

Full Gasket set
+ Multi-layered steel head gasket
+ Intake manifold gasket
+ Exhaust manifold gasket
+ Valve cover gasket
+ Viton valve stem seals
+ Camshaft front
+ O-rings
+ Front seal gasket
+ Rear seal gasket
+ Water pump gasket
+ Timing cover gasket
+ Other Small Gaskets

Oil Pump
Water Pump
Lifter Lash Adjusters ( 16 Pieces)

Timing Belt Kit
+ Timing Belt
+ Tensioner (made in Japan)
+ Idler (made in Japan)

Pistons with Complete NPR Ring Set (made in Japan)
+ Pistons (We have Standard and oversizes: .50mm = .020" )
+ Complete Ring Set (We have Standard and oversizes: .50mm = .020" )
+ Pins
Compression Ratio: 9.6:1
Standard Diameter: 87.50 mm
1st Group: 1.20 mm
2nd Group: 1.20 mm
Oil Ring: 3.00 mm


Engine Bearings (Either from ACL or King)
+ Main Bearing Set (We have Standard and oversizes: .25mm = .010" or .50mm = .020")
+ Rod Bearing Set (We have Standard and oversizes: .25mm = .010" or .50mm = .020")

Then i also figure that i will have to have the crankshaft reworked and the rod that has the bad bearing honed. I wont know until i get in there but should i have the cylinders bored also and what else should be done to ensure that the engine is in prestine condition let me know

Boring the engine block should only add another $50-75 depending on the shop, to the bill. Have them check it before you order the pistons so you know what size to get.

So from a few other threads that i have I am unsure that it is my rod bearing. I performed a test where you take each spark plug out and listen to the cylinders to determine if they sound gets lower or quits. Nothing...... I heard that it could be a bad bearing in my water pump? That it could be a bad pulley. Any ideas. I am pretty sure the water pump is leaking so it has failed. When i was breaking it down the timing belt looks like garbage so I am glad that i decided to change the water pump first. Any ideas or suggestions would be great.
The car is making a rattling/ noise almost like a lifter but the rattling is nothing like a lifter. It doesnt really change unless the car is ran for a while and then it starts to get a little louder but not overwhelming in which it starts to overheat. The rad resevoir tank even starts to boil.
