"옷 입어" may mean "I'm getting dressed" depending on the context.

옷 입어 : Put on clothes, Get dressed 팔이 안 껴저 (← 팔이 안 끼워져) : I can't put my arm through the sleeve.

걸음을 "디뎌" may mean 걸음을 "내디뎌" in the sentence you gave. 내디디다 (OR 내딛다) : step forward, take a step, advance So 걸음을 디뎌 can mean "start walking".

An analytical approach 1. 매일 성장하고 있지. It's growing everyday. 성장하다(grow) + 그리고(and) + 있다(~ing) → 성장하 + "고" + 있다. main verb + connector + auxiliary verb 2. 하고 싶은 말 words I want to say [말하다(say) + 그리고(and) + 싶다(want to)] + 은(used to make an adjective) + 말(words) → [말하 + "고" + 싶] + 은 + 말 → [하 + "고" + 싶] + 은 + 말 [main verb + connector + auxiliary verb] + 은 * words "to say" : "할" 말 3. 미안하고 고마워. I'm sorry, and thank you. 미안해(I'm sorry) + 그리고(and) + 고마워(thank you) → 미안하 + "고" + 고마워 It's "고" originated from "그리고" which basically means "and".

I might be wrong, but let me give it a try. ^^ 민호 suggested I should pay a visit, saying 혜미 might pour out nonsense. * ~할지도 모른다 : might ~ * ~면서[a shortened form of ~(라)고 말하면서 or ~(라)고 하면서] : saying * 가보다 : pay a visit * ~라더라고[a shortened form of ~라고 말하더라고 or ~라고 하더라고] : said that ~ , told that ~, suggested that ~, etc. (depending on the context)

Yes. You can use both of them.

 

안녕하세요. 저는 샐리입니다. 저는 <em>그루지야에서 왔어요</em>[OR <em>그루지야(에) 살아요</em>]. 

<em>난[</em>I recommend <em>저는</em> since you used <em>저는</em><em>(a polite form)</em> in the sentences above. <em>AGREEMENT]</em> 한국어를 배우고 싶어요. 제발 도와주세요. ^^

<em>만나서 반가워요!</em>

I'd say "미리 감사드립니다."(polite) for "Thank you in advance." Thank you for explaining [that] to me. (저에게 or 제게) 설명해 주셔서 감사합니다. (polite) (나에게 or 내게 or 나한테) 설명해 줘서 고마워. (informal) * to + person : person"에게"
