Lots of great advice here. Your local library may carry a few books on quilting that may get you started.
One of the things that changed how well I quilted, is starch. I now starch almost everything - makes piecing easier and keeps bias edges from getting pulled out of shape so easily.
I'd also bet that if you talked to some of the quilters in the local guild, even though you can't get there now, you may be able to connect with someone to ask for personal hints and help. Many guilds have working groups (for example to make comfort quilts) that you could join - those hours may work out better for you.
