Hi and welcome to Pixalo
To your question. If you like Macro then get the 100mm- it'll double up as a very good portrait lens then you won't need a 50mm. You don't mention sport, birds, wildlife etc so I assume you won't need a long zoom.
For landscape you are better off with a wide lens but you also need something for walkabout. To cover both those I would suggest the 24-105 rather than the 28-135 - it is definitely a superior lens. the kit lens is not the best but good for starters
However you won't get the 100mm and the 24-105 for under $450 so my advice would be to get the 24-105 if you can afford it. It's an excellent L lens which is an investment, it will last you for a long time, and it's a very good walkabout.
That's my twopenneth based on my experience of those lenses but wait and get others' opinions as well then bite the bullet
