Is it a better idea to not use daily indices?

The rollover and shrink APIs were designed to make daily indices not needed in as many use cases. It depends on how long you keep the data whether you need them.

How many shards and replicas should I use for my daily indices, given that my disks are in RAID0 and Elasticsearch will have to compensate for a failure?

With 1 replica you'll be able to stand a single disk failure until Elasticsearch recovers that indices that died. You'll want another replica if you want to withstand more failures, I suppose.
