I didn't really read through all the replies, so most of what I'll say is probably repeating others
Welcome to AC! Glad you found this place. I know it's been a lifesaver for me (and my fishies!).
1. Is the bio-wheel and power head setup the "only" way to go these days? For a fry/quarantine type 10g tank would undergravel and pump filtration be sufficient?
Bio-wheels aren't the only way to go, but I do like mine. I've not had any issues with the bio-wheels stopping or anything ... they do slow down after they get seasoned, but as long as I swish them out in old tank water now and then (every 2-3 months or so) and get any algae and gunk that's building up on them off they're fine. They also will not "kill ammonia on contact", well they kinda do, but not until the bacteria that lives in them is able to consume all the ammonia being produced in the tank. Anyway, they won't hinder your fishless cycle in any way.
What I do for my quarantine tank is keep a sponge filter going in one of my established tanks so it stays seeded with bacteria, then whenever I need to setup my quarantine tank I just take it out and set it up then throw the sponge filter in there and it's instantly cycled and ready to go. You can do the same thing by just keeping extra filter media in your filters on your main tank to transfer when needed.
2. How difficult are live plants and what sort of maintenance do they require? Are there good beginner plants?
I'm fairly new to live plants also, but they aren't difficult. I went low tech (no CO2 injection or heavy lighting). Plants are very beneficial to your tank and definitely worth the effort if it's something you're interested in. I'd suggest starting out low tech and go from there. If you decide to go planted, the lights that come with a tank at the LFS won't be strong enough even for low light plants (need at least around 1 watt per gallon or WPG), so if you can purchase just a bare tank with no hood you can just get glass canopies to cover it and put lights above that (shop lights or whatever you can find at the hardware store). If you're handy, you can even build your own canopy to mount the lights in and save a lot of money that way. Setting up a planted tank can be on the expensive side if you go all out, but you can do it cheaply also. Read up in the planted tank forum, lots of great info there.
3. I know for a fact that I want a number of neon tetras, what sort of other (maybe bigger?) fish are complimentary to them and would work well in a 29g FW? It appears from my reading that mollies and guppies would really rather like a bit of brackish water, so I don't think the neons would appreciate that.
I love keeping bettas in my community tanks, but I'm pretty partial to them
Many people think they can't be kept with anything else, but they do rather well with most community fish, with a few exceptions of course. Another fish I've started keeping recently are Endler's livebearers. They are related to the guppy, but are a bit smaller and quite colorful.
4. If I went with a 55g...
5. Can anyone suggest a good online source for aquariums and supplies? We do have a couple of stores locally that have fish and supplies, but I do want to shop around.
I like
www.bigalsonline.com and
www.drsfostersmith.com for buying supplies. I've also bought fish from people at
www.aquabid.com (like eBay for fish!) and I hear great things about
www.liveaquaria.com

I am doing the fishless cycle now, I have a friend that said he would do it but not trust it and suggested adding 2 fish at a time, I am not sure which way I want to go
There is no reason not to trust a fishless cycle. The process is identical to doing a cycle with fish, only you don't have to deal with doing excessive water changes (sometimes twice daily!) to keep ammonia and nitrite levels down so they don't harm/kill your fish. Both ways you're simply adding ammonia to the tank, it's just easier and less work to do it without fish and if you screw something up all your fish don't die

I am tempted to get all the fish I want after the fishless cycle is finished.
That is exactly what you're supposed to do! That's the main thing I love about fishless cycling is that once the cycle is done I can fully stock my tank in a single day. If after a fishless cycle you only added 2-3 fish, then within a few days (week? not sure how long) all the excess bacteria would die off and your tank would only be cycled to handle 2-3 fish worth of waste. Then when you added a few more fish, you'd see small ammonia/nitrIte spikes or mini-cycles until the bacteria multiplied enough to catch up again.
Hope that all makes sense. Glad to see both of you getting back into the hobby.
