I don't know those controls!
With regards to the numbers, just wait til you get #5 with longbow. That and #2 are favs. (For pistols I think it's #3 I like but it's similar to #2 with a bow; at least longbow - I can't recall what options the short bow has...)

and you ought to open those chests, you know... (I can't recall seeing the first, red, icon on that row... what's that?)

oh and did you notice that sylvari can be bioluminescent in the dark?

Maybe you should skip the research and just PLAY? Click the little wiggling icons to the lower right: you get something every day you log in, you get rewards for filling those hearts, and for leveling up of course. They also have some daily quest type things, where you get rewards for each and a bigger reward if you do all five. I think. It's been a while since I bothered with the dailies.

Hearts give you karma and coins and also lets you buy things from the people who had that particular heart over their head. Sometimes you can get better weapons, armor or trinkets, sometimes they just sell... well, less interesting things, like stones.

Items called "trophies" are basically junk items and going to anyone who sells things, you can opt to sell junk, and clear up your backpack some. Crafting materials can also all be moved to a crafting inventory kind of thing if you click the little cogwheel at the top of your backpack.

I think you can use two weapons from level 7 or so? Not sure, but it takes a little while before you can equip more than one. Eventually you'll also be able to swap between two weapon setups using the § key. (Uhm at least that's the symbol on MY such key...)

And as for making choices, it usually doesn't make much difference. The items are usually comparable in both effect and value. But if it's armor, you might want to choose something either of the type for your character (cloth, leather, heavy) or a skin you haven't unlocked yet. Same thing with weapons, really. All items may have little things attached to them (I've forgotten what they're called...) that can increase damage, precision etc. So you can also make your choice based on which attribute you wish to increase.

Glad you're enjoying yourself

You'll get more and better bags as you progress. If you're "old enough" to use the trading post you might be able to pick up some 8 slots bags cheap. (I think the maximum number of bags is 5? Though one can purchase more bag slots for each character, for gems).

And don't worry about the wwwwwwww. At least you didn't post it to chat. I keep doing the same thing, but when I'm trying to divide stacks in my inventory I somehow always end up sending actual messages to chat. "[chain leggings]" or something. Out of the blue. But hopefully we're not the only ones...

And the great flappy thing was probably another user on a flying dragon mount

Speaking of freezing the camera, you can do that in No Man's Sky and that's an MMO. I haven't really paid attention to whether it just freezes your view, or actual time, though... Freezing time could be annoying if people keep trying to take screenshots where there are other people...

EDIT: Chain leggings was a really bad example as they don't stack...
