Learning about seven tools sounds like a survey class, by which I mean, the class likely gave you some time to learn about each of the tools but without time and project experience, your knowledge will have limitations. Look for project work that helps to supplement what you've learned academically. You might consider focusing on one or a couple of tools; as it's not likely you'll be able to stay fluent and current with so many tools at the same time.
Working from home is an understandable desire. Saving commute time and balancing life needs can be great, but here are some factors to consider: Will you have the computer equipment to address your job needs? Do you expect a company to provide the equipment? Do you have the environment and discipline to work from home? You might consider targeting nearby companies so that you can mix some office time with some time from home as you adjust to working from home.
Software testing can be a career filled with great variety of intriguing project work. I wish you well on your path to learning.
