You do need FastEthernet interface. You cannot create a sub-interfaces from a regular Ethernet interface. So, you cannot use a router that doesn't have a fastethernet interface in a router on a stick configuration

try using ISL as the encapsulation. And if the router has a AUX port you can get a dongle that will turn it into a ethernet/fast ethernet port

its usuall not a good idea to use vlan 1 as your management vlan for security reasons.

make sure to trunk the interface directly conecting the switch to the router.

And no, you dont need a Fast Ethernet interface to do encapsulation.

For 2600 series routers, I had to do a “no shutdown” on ethernet 0/0 interface for the trunk to come up and work properly.
