Very good question. If you sweat a lot give a little sprinkle of talc powder, cheap. The latex are a necessity once you use them, working for Boeing for a year got me hooked. Also great for house work.
For the hot surfaces I use the "Mechanix" gloves, they are leather palmed with a nylon backing, sensitivity and breathability is great and you can handle anything within reason without burning yourself, time will tell as I just bought them but they seem like no DIY garage should be without a pair (PepBoys, Schucks, etc). Good Luck.
