well, I think 0.0.0.0 should serve the same purpose as 0.0.0.255 as the
later already defines a specific interface. Any mask that is more specific
than the interface original mask is meaningless.
I will also use sh ip eigrp interface to make sure the corresponding
interface involved in EIGRP.
For passive-interface default, that's only apply to RIP since no wildcard
mask is allowed when using the network command.

Do u think network 10.10.10.1 0.0.0.0 more safe? Does Cisco encourage people
to use it?

Passive interface is a command to make an interface passive (meaning not
sending any eigrp advertisement). If memory serves me right, it does not
influence whether an interface would be an eigrp interface or not. If the
interface is listed under the network command and you use passive on that
interface. That interface would still be regarded as an eigrp interface
with no neighbor.
From pass experience, the exact network statement should suffice, however
should you decide to play it safe, it never hurts to put toy around with
passive-interface.
Example,
int e0/0
desc --== EIGRP interface ==--
ip addr 10.10.10.1 255.255.255.0
!
router ei 1
passive-interface default
no passive-interface e0/0
network 10.10.10.0 0.0.0.255
end

UNder EIGRP, when asked only advertise on specical
interface, for example, interface ethernet 0 address
10.10.10.1/24
Is net 10.10.10.0 0.0.0.255 enough?
Do I still need to configure
passive-interface default
no passive-interface ethernet 0
