Graeme makes a good point there.... If you're going to buy a Talon auto then be prepared to keep it a talon auto. You want a Mitsu/5 speed though, so buy what you want, expecially because you said you're a noob, so it means you'll be buying labour.
To buy a Talon auto and convert to a Mitsu stick and to stay in your budget you'll be looking for an older, higher mileage, worse shape talon, then immediately spending many thousands of dollars (6+?) to turn it into a high mileage eclipse with a whole hodgepodge of parts in it.
Instead you should buy a better condition, lower mileage eclipse 5 speed that is what you want. You'll be happier that way. Either that or just decide that you're happy with a 2G period and get a talon or eclipse. Personally, I like the styling of the late 2G talon better than any of the other 2Gs, but that's just me.
