Yeah, no need to buy a kit with stuff you'll never use. Get the one tool you need when you need it and it will still be less than what you would have spent at the bike shop getting it fixed there.
For starters, just get a set of metric T handle Allen wrenches, tire tools and a pump.
After that, the most useful tools are probably a cable cutter and chain tool.
