Anyone got any tips on how to remember the names of the different techniques? They're really hard to remember for me 
First of all, do not worry one bit

Not only are you learning new techniques but learning a little japanese also and you are not alone in thinking it difficult! Everyone already has given bang-on advice. I too found *speaking* the words a particular help. And repetition is beneficial and of course, the more training the more benefit. I bet you can already count to ten just by hearing and repeating.. ichi ni san shi. Also, as
Kacey and
Sukerkin suggest, and what helped me initially was to make sure that somewhere you can see the words *written down*. I remember hand writing all the words myself which is another thought. Why? Because visual memory is the most developed in us. So you just visualise the names when you work the technique. There are lots of additional mnemonics for remembering the names like attaching a silly or pertinent image in your mind to the name of the technique because again, pictures are easier to remember than anything. As
theletch1 says, the more senses you have working for you, the better. For me it was just simple repetition (and which will absolutely come to you with time) and visually picturing the name when doing the tech. Take a second when you are pinned dreadfully on the floor in a nikkyo to tell yourself, ahh, nikkyo!!!!

And but seriously, do not be concerned at all. No one would expect you to memorise names exactly until a little later. I wish you sincere good luck with your training
