Ah-hah! You want to play with the big boys, eh? Good for you. As far as getting out, it's as good or better than buying an amplifier. CW cuts through when SSB becomes just a muddled mess.

You can also practice on-the-air receiving using W1AW's daily practice sessions.

I recommended my students start with a straight key, then incorporate a bug or paddles into their repertoire. You can find hams carrying on slow-speed QSOs on or around the Straight Key Century Club (
skccgroup.com ) calling frequencies. 7.055, 7.114, and 7.120 MHZ are especially popular. We also have twice-monthly sprints, one over the 2nd full weekend in the month, and a 2-hour sprint at 0000Z on the 4th Wednesday of the month (Tuesday evening in the US). They're very low key (pun intended) and excellent practice if you want to jump into full-bore contests later.
Go ahead and learn the letters. The words will take care of themselves as your skill improves. Soon CW will become a second language and you won't even think a bout it. FWIW, I've been on the air since 1954 and dabbled in AM, FM, SSB, RTTY, and data, but always come back to CW. Very seldom do I pick up a microphone these days. Sending CW takes much less effort than talking.
Record your sending and play it back to compare with machine-sent CW. If you have code reader software, send to it and make sure it can copy your "fist". The old ones are best for this purpose because it takes well-sent CW for them to decipher it.
