most indian cookery books use tons of dry spices which are roasted then ground, usually becayse they are north indian recipes. I'm south Asian we use mainly ready ground spices and whole spices thrown in. I get bored so I do have some indian cookery books to make things quicker I use the ground spices often instead of grinding whole spices, much quicker, will make your life easier.
Also don't believe that crap about it tasting rubbish, it really doesn't it just tastes a bit different but still very tasty. I use both ground spices and when I have time I grind my own spices its a slightly different taste one is not inferior to the other.
I also wouldn't grind bay leaf or cinnamon or cardamoms , in indian recipes I find the strong flavour of cinnamon ground in curry off putting, maybe I'm not used to it I always use whole.
I'm not sure about simple indian cookery books the one I turn to a lot because almost every recipe is delicious "50 great curries of India" Camellia Punjabi. ive used madhur jaffrey veg recipes not been too impressed by tastes to be honest, ive had better ones using youtube. but ive not tried her meat recipes so give it a shot maybe borrow a library book instead of wasting your money on a book you may not like?
for western/European recipes I search bbcgood for tested and rate recipes. ive also used a few Jamie oliver ones, I think he does no frills really well, and jo pratt.
When I want something fast I use Chinese or thai recipes, I wish I was from that region its quicker than a curry I don't think a good curry can be made in less than 1 hour, but good oriental food can be whipped up in 20-30 mins.
I think you lack confidence OP relax enjoy it. if you're stressed I wouldn't encourage batch cooking. When I cook 4 curries I get stressed, I never used to, maybe its coz I have more ppl to look after, I just hate it. I'm happiest when I make just one main dish, but that rarely occurs.
