Reaper is a scrypt coin GPU miner. PPC (BTC,TRC,FRC) are SHA-256 coins.
You can use any miner you use for BTC. I suggest CGminer . It does both SHA-256 and Scrypt, but it defaults to sha-256.
If you want to use Coinotron, you will need to register first. You use the same ports with most of the coins on coinotron (8322 or 9322). In your account, you set your workers to what coin you want to mine.
Dunno why I thought PPC was Scrypt, need more caffeine.
Have a rig using CGminer, problem with it is high thread concurrencies arent well supported yet. Dont know if that'd apply with SHA.
Registered and worked added, I'm not that noob

Nope, thread concurrencies are not used with SHA-256. Shader, concurrencies and gap set to zero.
Example from one of my rigs:
{
"pools" : [
{
"url" : "http://coinotron.com:9322",
"user" : "xxxxxxxxx",
"pass" : "xxxxxxxxx"
}
]
,
"intensity" : "5,5,5",
"vectors" : "2,2,2",
"worksize" : "128,128,128",
"kernel" : "diablo,diablo,diablo",
"lookup-gap" : "0,0,0",
"thread-concurrency" : "0,0,0",
"shaders" : "0,0,0",
"gpu-engine" : "0-900,0-900,0-900",
"gpu-fan" : "0-65,0-65,0-65",

"gpu-memdiff" : "0,0,0",
"gpu-powertune" : "0,0,0",

"shares" : "0",
"kernel-path" : "/usr/local/bin"
}
CGminer is natively a SHA-256 coin miner, and a pretty dam good one (in my opinion of course

). Scrypt was a recent add on to CGminer, and not as finely tuned as it's SHA-256 coding.
