Welcome to Canreef.
I would check our buy and sell for liverock. Plenty of good, used, affordable stuff around town, and it will already be cured. This will help reducing your cycle time.
I've got a 65 gal and I'll tell you I wish I went bigger. Get the largest tank available for your space and budget. You'll be glad you did in a years time when the addiction will really take hold. With a larger tank comes the opportunity to add larger fish like Tangs, which will help a lot eating algae (everybody gets algae) .
Lighting is a personal choice. If I could do it again I would do an 8 bulb T5, but that's just my preference. I'd recommend watching BRS's 52 weeks of Reefing on YouTube. They just started getting into lighting options. An amazing series I would highly recommend to any newbie.
...and just because I'm feeling a bit mischievous, I'm going to say that Kessils are probably the best LED's on the market!
Keep us posted, and I'm looking forward to your build thread.
