With respect to your second post:
-The armors you can get from Ascalon City are both better than the upgraded Pre-Searing set. It's nothing revolutionary, just a better version of what you started with. There are a few different sets but they differ only in appearance.
-Play whichever profession you want. Playing something you don't like for whatever reason defeats the purpose of playing in the first place. I wouldn't turn your back on the Ranger based on your experience thus far - the issues you're having will have occured regardless of which profession you picked.
-People recommend Rit because there are builds you can run which are effective even if you have a single digit number of brain cells. This is ideal for GW2 players who play GW1 just for rewards in the former. If you actually give a damn about GW1 you ought to not feel any incentive to play Rit just for the sake of it. All professions are perfectly capable of completing the content so focus on finding the one that suits you the best. You can always make more characters to see how you like them.
-You don't have a lot to work with so I won't be critical, but in terms of builds:
--Power Shot is trash. It's just x damage rather than +x, and if you're not underleveled/facing other rookie issues you'll be spending a skill slot and 10 energy on what amounts to nothing more than an auto attack. If it's worthwhile now then ok, but keep in mind you ought to outgrow it.
--Generally speaking you don't want to split your attributes more than three ways unless you have a good reason for doing so. For a Ranger, Expertise and a weapon attribute (Marksmanship is the only one Rangers have natively but you could get others with the relevant secondary profession) are a given. If you want to take a pet, which you should at least for now, then Beast Mastery makes three. If you want a heal (also a good idea, at least for now) your best bet would be Troll Unguent, which is in Wilderness Survival, so you'll have to split four ways in that case. Heavy attribute splitting is something that plagues Ranger builds generally, so I wouldn't worry about it. Just don't go for five. That's never worthwhile.
--To be clear, you pick a primary and a secondary profession. Those labels are very deliberate. You are a ranger. You do ranger things. Your secondary is there to supplement your primary. If you take /Monk to be a healer or /Elementalist to be a nuker you're doing it wrong. What you should do is look at particular skills in other professions that you can use to complement your existing skills. Given you're /Monk, something like a reusable resurrection skill and maybe a hex removal would be the things you'd look at. Bane Signet (with 0 Smiting) could be worth keeping just for the knockdown. Also know that later in the game you'll be able to switch your secondary freely later while you're in a town, so if you end up not liking Monk you can try whatever else you like.
-A list of skills obtainable via quest can be found here. You can also check skill trainers for new skills.

With respect to your third post:
-Henchman levels are based on the outpost you got them from. So Piken Square has level 6 ones, but if you went back to Ascalon City they'd still be level 3.
-Ignite Arrows, presumably. Combining it with Dual Shot makes for a nice punch. GW1 has scatter mechanics, so they will flee after a time. At least if they're moving they're not attacking or using skills. I don't know what you mean by "cleave damage".
-I've undoubtedly got some bows in storage which are trash for me but useful for newbs. Add me to your friends list (Marty Silverblade) and I can give you one. Hopefully our timezones overlap.

As an aside, Nicholas the Traveler is collecting Charr Hides this week. If you want to make financial issues a thing of the past, at least for the medium term, you'll want to trade hides for gifts. You can obtain a maximum of five. Each (UNOPENED) gift can be traded for ~4 globs of ectoplasm, which can in turn be traded for 6000-8000 gold. Here is his current location. He'll move at the end of Sunday (American time, not sure exactly when or what that is for you), so get on it. If we meet up to trade bows I can give you a hand with this if you need.
