Packing your rucksack - put the things you need last at the bottom - usually mat, SB and spare clothes. Put the things you will need during the day at the top or in outside pockets. Have the tent where you do not need to empty your pack to get at it. Common Sense Rules!
As a tea drinker - I suggest you find a variety of tea that you are OK with, that you don't mind drinking sans milk - eg. Earl Grey. Milk is just a hassle in tea/coffee when camping. IMHO.
Nuun (there are other brands) tabs will not only help with 'salts' balance etc. but I find they encourage me to keep hydrated better. I make one up when I stop at the end of the day and as I get up in the morning.
Take a micro fiber cloth (cheap kitchen variety) for moping up tent and everything else - keep handy.
