I have old tapes - but yes, search amazon! There are resources (books with CD's) for learning Torah cantillation. For nusach generally - the USCJ book service sells a complete set of EVERY prayer service on cassette tapes (which I dearly wish they'd transfer to CD's soon). Aish does too, but they aren't the same tunes my shul uses - you'll want something as close as you can get.
There are also various online resources where you can download mp3's of certain prayers - Let me hunt around a bit for some urls and I'll post them.
Posted some links under Jewish books and music - I think. Or somewhere! oops.
Use the 'search' feature (top menu) and look either for me, or for posts in the past couple of days.
One thing I did early on, was ask a friend with a great voice to MAKE me a tape specifically for Shabbat Shacharit. I would listen to it over and over.
Also look for Tara, for CD's. I posted a link to the Meyer Davis CD, Shabbat for Starters. It's got the blessings, and Grace After Meals, plus typical 'home' Shabbat songs and it comes with a book, too. You can find it probably from Hamakor (the Source for Everything Jewish) which is pricey though. www.jewishsource.com/
Did you not find what you are looking for in my long lists of online sources under the topic "Topic: tapes, CDs, online...."? My posts are called "Online davening audio files" and "list of 33 online audio websites" Most of the sites use Israeli pronunciation.
By melodies for Haftarah, do you mean the melodies for the blessings before and after the reading (which are the same except for special readings), or do you mean the "tune" for the Haftarah reading? The reading is done with Haftarah trope ("cantillation") indicated by the little symbols above and below the letters. Thus chanting is not a given melody, although there are certainly combinations of "notes" (really a few notes per symbol) that tend to occur. It is similar to Torah trope in that the same symbols are used and are called the same names and the tunes for each symbol are similar, although the tunes for Haftarah are in a minor key and tend to be more embellished than their Torah counterparts.
Chanting Torah or Haftarah is beautiful and fun to learn and do, but not what you want to focus on at first. It is required for you to say the main prayers (e.g. Amidah), but not to chant Torah, each day (study Torah yes; chant from the Torah scroll yourself, no, although Torah reading is part of the morning services of Sat, Mon and Thurs., and Sat afternoon)
I would focus first on learning the Shabbat Shacharit service, then other parts of the Shabbat morning service, then Kabbalat Shabbat, and then the afternoon/evening services and weekday services. For those the wording is also fixed so you can and will learn a lot by memory. There are lots of recordings of the various services in the links I posted on the other thread.
That said, I love chanting Torah. I do so about once or twice a month for both of my lay-led minyanim where members take turns doing all the Torah reading. I will do my first Haftarah reading this spring on the Hebrew anniversary date of my conversion.
The first link on my list on the other thread should suit your purposes quite well: www.caa-austin.org/religious/index.php?page=shabbatserv#shabbatatcaa It has audio for all of the Shabbat services from Friday night through Saturday afternoon. It is keyed to the pages of Sim Shalom, the standard Conservative prayer book Note that there is the regular version of the siddur which has Shabbat, weekdays, and festivals, and then there is the smaller Shabbat/festivals version many people call "Slim Shalom" (because it is a smaller book--get it? ) I recognize the page numbers on the above link as those of the regular siddur version.
If you don't have a copy of Sim Shalom already, or if you want transliteration, you can get the text from this website (also indexed by Sim Shalom page numbers): kakatuv.com/conservative.html[/url
Start learning the Shabbat Shacharit service, and within that service, start with the Amidah which is the most important part. Or if your congregation does the "V'ahavta" first main paragraph of the Shema out loud together, you might want to start with the Shema. It is in some ways the essence of Judaism and was the first thing my sponsoring rabbi taught me about when I started to study for conversion.
By the way, the audio above is standard Ashkenazi tunes (heard in Conservative and Orthodox shuls) using "Israeli pronunciation" of the Hebrew. I'm pretty sure it is what you will hear at your shul (shul = Yiddish for synagogue, if you didn't know that already) and what you want to learn.
