Giant XTC Single Speed MTB Project

**To start off the thread I thought I'd let you in on my story.
I'm 24 and I'm from Wolverhampton, when I was younger (15-18) I used to ride all the time, then one day I decided to pass my driving test and the riding stopped. My bike at the time was a Norco kompressor I'd built up over the years from just the frame, ended up just sitting in the garage and every now and again I would ride the bike to work on a nice day. Fast forward a few years and I decided I would ride more and I need a bigger frame. So I went on eBay and came across a Giant XTC SX frame (can't remember how much I paid for it) so I bought it. When it arrived I stripped the Norco and built up the Giant, I used it for a bit and I kept having problems with the gears, so I just put the bike back into the garage and forgot about it.
So recently I decided I wanted to get back into riding, so I set about doing some research on single speed conversions and just bought the parts needed: 24seven single speed conversion kit 17t and a gusset chain tensioner, I kept the 32t chainring I had on the front already, eventually I will get a single speed ring. I also started buying the tools I would need to build the bike as I went along. I rode it about 6 miles and noticed play in the bottom bracket, so I bought a truvativ gigapipe BB and fitted it, now its as solid as a rock. I also noticed the chain line wasn't perfect and it was because the mech hanger was bent, I'm still waiting on the new hanger to come in the post, there are a few things I still would like to do to the bike, hopefully some of you guys and girls could give me some ideas on what to do and what to use.
the chain tension will be sorted once I have the new hanger fitted. **
