Two options - 1. Enable - spanning-tree portfast bpdugaurd default. 2. use the inbuilt macro - switchport host can't remember which - which basically says a host is connecting to this port so put it into forwarding ASAP, use a interface range command to apply to all interfaces required.
With regards to loopguard, this one has me a little confused to. So we know loopguard says prevent unidirectional loops on trunk links (or interconnected switches), we know that we should apply this to non-designated ports. So these are all alternate and root ports. If you look at your show spanning-tree configs, I bet that most of these ports are your trunks. So I'd say you can apply loopguard on all your trunk links. Hope that helps.
