2005 STS V*8, Hard Start issues, also will not start with remote, smell of gas when it does start, OBD codes P0300 and P0442

The remote start won't work until the codes are cleared. It could be lots of things so I'll let a member with more experience with the codes make suggestions. (I still have more than 6 months of CPO remaining, so I'd just make am appointment with the dealer.)

Good Luck!

The P0300 is engine misfire and the P0442 is Evaporative Emission Control System Leak detected. I don't know what the cause is.

Emission Control System Leaks can just be a loose gas cap. A misfire code doesn't tell us much.

Is the hard start issue in all conditions? Hot, warm cold, wet or dry? Any pattern at all?

Could be a bad coil or fouled plug this can cause excessive unburned fuel resulting in the fuel smell. Since each plug has its own coil probably need to get diaganostic done.

Does it have the original plugs? How many miles?

If replacing plugs, use only OEM.
