Engine Rebuild Advice - Summit re ring kit, etc

My 306 in the GT only has a couple thousand miles on it, but it has a bad ring in cyclinder #5 due to the un-tuned supercharger combo it had when I bought it. The s/c is gone and I just want to get the thing freshened up w/ new rings and gaskets to stop the leaking gaskets too.

I've been looking at gasket sets, and re-ring kits at summitracing.com and have found this kit:

Are the rings included in that set good rings? They only sell for like $34.95 if you buy them alone. Do I need expensive rings or will those be good enough for a mild 300 hp combo?

Additionally, should I have the internals balanced? I don't plan to rev crazy high and the car won't see much track time. I don't plan to get the heads milled either because they were just cleaned up and inspected when I changed head gaskets about 300 miles ago. I want to sell it when I get it fixed, but I'm sure I won't be able to let it go. I need to get it fixed, but I'm on a budget too.

Also, the damper wobbles....should I buy a new stock damper or is that due to the crank?

I know $35 won't get much, which is kinda why I'm asking.

I was originally planning to buy the fel pro gaskets I need (all except head and valve cover gaskets) and Total Seal conventional rings ($99 @ summit). I'd then buy rod, main, and cam bearings, an oil pump and ARP shaft.

I'm not sure about a new balancer or motor mounts yet.

as far as that goes, would it be totally stupid to wait and pull the bearings out and see how they look? Then, if they look ok, just re-use them? The engine should only have 1000-2000 miles on it if the dude I bought the car from told the truth.

The rings I mentioned earlier (sealed power moly rings) I got from NAPA, they cost like $109 and have a moly top ring. Sure you can get them at summit for $99 but they charge you $9 handling and you have to wait like 3-4 days. Also I got my engine bearings from NAPA. Pretty much same price as summit. my $.02

I don't understand the differences in a few different sets of rings, still.

I searched on summit and compared 4 sets of rings:

SLP-E-251K030 - $34.95http://store.summitracing.com/partdetail.asp?CP=1&part=SLP-E-251K030&N=0&Ntt=TSR-CL909030%20or%20SLP-R9903030%20or%20SLP-E-377K030%20or%20SLP-E-251K030&Ntk=&rsview=sku&Ns=P_SRE_DisplayPrice|1

TSR-CL909030-$99.95http://store.summitracing.com/partdetail.asp?CP=1&part=TSR-CL909030&N=0&Ntt=TSR-CL909030%20or%20SLP-R9903030%20or%20SLP-E-377K030%20or%20SLP-E-251K030&Ntk=&rsview=sku&Ns=P_SRE_DisplayPrice|1

I can see a few differences on the TSR's: Top and 2nd ring material is cast iron (isn't that bad?), 2nd ring is gapless, low oil ring tension, and something about Claimer Moly?

Other than that and the SLP-R9903030 rings have a plasma-moly facing material, they're all about the same, but vary from $34.95-99.95. I understand you get what you pay for, I would just like to understand more what exactly I'd be paying for.

Thanks!
