I'm definitely no great CSS designer from the standpoint of responsive design. All my designs are usually not responsive to the point of multi-device, but will scale up/down for standard monitor ranges, etc. They work on tablets generally, but not on cell phones.

I won't have a choice soon because the software I use for my site is going responsive in the next incarnation. It'll be a learning curve, but should be fun/interesting.

As for tools, I generally use notepad or right from the ACP. I also use colourzilla to find colours, etc.

You may not be as good with the semantics and technical details, but you have a knack for envisioning an idea and making it happen. That's the key to a great designer right there.
