If they're available on Amazon where you are, check out Ohuhu markers. They're so much cheaper, and work perfectly fine. You can start with them and replace colors you find you use a lot with more expensive brands as they run dry. If you have Tiger stores near you, they also offer small packs of alcohol markers that are worth trying out. The cap colors don't match the ink inside well, but both these brands work fine. I can't really tell the difference between them and my Copics, except they don't have brush nibs.
For paper, smooth is good. Don't use sketching or watercolor paper. Bristol is great but can be expensive. I like high quality printer paper for everyday work/practice. Look for "cover stock," which is a bit heavier and should be smooth. This is my favorite, though you may need to try a different brand since I'm in the US.
Just wanted to make a mention the paper I use because I get asked, and this stuff is a good deal. It's heavy paper for laser printer and its really good at picking up marker-- although it can be a little bit thirsty on them.
and then if you cared to see any more of my art:
