My two cents:
if you aren't up for a long jog back, don't stray too far from cities when sampling ect, at least untill they get vechcles out. i did this once and had to run and run and run and run for half an hour to get back. it's very easy to turn on autorun, bring up your surveyer, and hunt for resources, and not realize how far you've come. this is obvious, but thought i would put it in anyway.
if your waiting for a shuttle with a group or just some frendly person you met, try having some fun with each other. try commands like /pillow, /bonk, /bodyslam, /headlock, /bang, or /hack for a laugh. check ctrl+A for more of them! just another thing i thought i'd throw in. and also, there are variations for all emotes. putting self after it or a target name after it does something a little different. ex: "/bonk" by itself does this: bonk! bOnk boNk! but going "/bonk self" does: you bonk yourself on the head. look at all the birdies!
i know this is for "did you know?" things, but i thought i should put that in there too.
now for the useful stuff:
Artisans: Did you know?
if you're having trouble finding resources, and can afford to spend around 3000 credits (for most of them) you can buy resources in great quantities in the bazzar. a little obvious but theres more:
doing crafting jobs DOES get you crafting exp. keep doing them and you be leveling up soon.
General: Did you know?
you can swim forever. don't be afraid to swim in that ocean to get to the other side! (at least, you could last time i checked, haven't logged on since last update)
don't keep your weapon drawn all the time. i'm not sure, but i think that creatures have less chance of attacking you if you don't appear hostile because you have no weapon drawn.
if you don't have much exp in fighting, then rori is the place to be. usually just outside the city walls yuo can find packs of "frail squalls" little bunny- like cretures that can be killed easily from afar. often, after you start shooting, they won't even attack back. pick em' off, gather there exp and resources (bone, meat or hide) and eventually you have enough exp to go after the bigger creatures. but watch out, make sure there is no large squall in the area, if you star attacking frail squalls with "mama" around, it will attack, i think. and clobber you probably. it's like, 4 times your size. but the frail ones are only the size of your pistol.
typing lol (no, you _DON'T_ need a slash for this one) automatically makes you character pose as if hes laughing.
To have fun: did you know?
try talking to yourself. just for fun, i sometimes go beep beep boop beep bzzt or something near an astromech, and pretend i'm talking to it.
and sometimes, when i'm alone i go fhfkdhfdjshfjssjfkjsfh VOCAL MODULATOR FAILURE sdhfsfsjdhgfjdhgjkfdhgjfdhgdfjgh or some thing. it looks pretty funny.
someone else said to strip yourself naked. well, i have to agree with him. of course, you aren't really naked, your just in your underwear. try talknig to a few NPC's. i'm not sure it will produce a different response, so find out for yourself. and if any player comes along, go EEK! or something and run away. this is great for a laugh.
mabie you could also try pretending you're a crazy hobo? (say crazy stuff and sit in a corner muttering)
anyway, that wasn't too much info, and i don't have any really advanced tips, but i thought i may as well add these.
