I've been using those for larger projects. Another tip someone gave me was to try bamboo knitting needles and they are really nice. They're light, warm to the touch and just seem easier to hold. I've also been experimenting with different needle sizes to see if any of them are easier to hold, I have everything from a 5mm right up to 25mm.
For crocheting, I use an ergonomic base that just screws on the individual sized hooks - I love it! You barely need to grip it and can hold it in several different positions and are less likely to cramp with it. I just wish it was easier to screw the hooks in but I generally use the same size plus they've loosened up and are easier to screw in nowadays.
For free patterns, go to each of the wool companies and check out their free patterns. Lion Brand, for example have a search engine where you can type key words of items you want to make or tools you want to use - there are hundreds of free patterns. Paton are another well known brand - haven't checked their website yet though.
