Hi there and welcome! I've only just joined too but here's what I've managed to pick up in about three weeks...
Know your cycle- make a fertility calandar or chart with fertility friend
Know your body- cervix postition and CM
Evalutate your diet- make sure your eating right
Take a vitamin and make him take some too- Prenatals are good for you and he should take vitamin C and Folic acid (can increase the swimmers by about 400%, yikes right?

)
Read up on personal lubracants- there not all good for sperm, I just read last night that olive oil and egg whites are sperm friendly. (personaly not sure if I'd use egg whites... but olive oil I'm considering)
Buy an OPK- I've just been using Clear Blue with the lines, retails for about $16. US as it's my first month, but many of the girls here use the Clear Blue monitor which you can pick up on ebay for a steal if you don't have the cash to drop on it.
Read through the posts on TTC- All sections are extreamly helpful.
Google is your friend- I've searched lots of silly questions and have found lots of interesting websites.
And lastly and prob most importantly- See your GYN for a check up and stamp of approval.
Best of luck to you TTC and I hope this helped. See you around.
