personally, i've been looking for similar books just to learn, not to use. i found one on google books, have read the first chapter, haven't read any further [sample] so i can't give you a 100% yea or nae on the book. if you're interested though it's called The Little Book of Curses and Maledictions for Everyday Use by Dawn Rae Downton.
for meditation, go for some book on basics really. there's articles on this site that can help you along with anywhere else on the web really.
herbs, there's many books on the topic. currently i'm reading Earth Power by Scott Cunningham, it's got information on herbs in there, but it doesn't focus on it. he does have another book Magical Herbalism: The Secret Craft of the Wise that'll help you.
summoning, not too sure where to find a book simply on summoning. i have a few books about demons and astral beings, but it dives a lot more into the history, their strengths and weaknesses than summoning.
