The closest approximation I can get to ć is the Hungarian ty, which is a similar sort of sound, but still different. I can pronounce "tube" Britishly though.
I'm learning Serbian pretty much all day every day especially since it's summer and I'm bored out of my mind visiting my mother, far away from my real life in Hungary. And before that I had a sprained ankle so I was doing nothing quite a bit and had a lot of time for reading. I've got a really good book "Teach yourself Serbian". The book says you can find it at
http://www.teachyourself.co.uk. I listen to music in Serbian pretty much all the time, but that's not the best way to learn because they use a different word order for singing than speaking. Confusing!
I read forums: this one, and some fan forums for some Serbian singers I like. The games are the easiest because you don't have to be able to write long intelligent paragraphs.
But I'm starting to write longer things. I'm reading Harry Potter, found it in Croatian online. I make myself write stuff everyday. I watched a few movies in Serbian, but it's really hard without subtitles. I have to watch several times before I can laugh at the jokes. I read the forums with a dictionary and that's really good for vocabulary and I'm starting to rely on it less and less.
There's also a forum at phrasebase.com for foreigners learning Serbian, but it's not very active.

But yeah, basically just try to immerse myself in the language as much as possible. My interest in Serbian is almost autistic. (I'm not autistic, but my method of learning Serbian isn't that different from an autistic person's level of concentration and fascination with memorising a perpetual calendar). I try to think in Serbian. I try to use echolaelia in Serbian, which is really useful for working out word order and usage for certain words. But my echolaelia isn't very communicative yet in Serbian. (It is for the most part in English).
You probably have less time than I do (I'm a bored college student home for the summer), but I'd recommend maybe listening to cassettes in Serbian even if you don't understand while on the tube to work or trying to think in Serbian as much as you can.
And Harry Potter's great, because it's written for 11 year olds.
Oh, and you can find subtitles in Serbian for plenty of movies online, just google them and you'll find stuff. So you can watch movies in English and read subtitles in Serbian. Hope that helps.
imam 24 godine. Živim u Mađarskoj već sedam godine. I hvala Bogu nemamo rodove. Dosta je da imamo oko 25 padeža. možeš da komuniciraš sa mnom na engleskom i ispravljaću greške. I ja bih volela da znam kako bi izgledale moje rečenice bez grešaka. 
i naucices jezik kao od sale:)
