Sounds like everything is going to plan

2 solids meals at 8 months is absolutely fine. A lot changes between 8 and 12 months too, it's longer than it might sound and you don't need to rush towards those 3 meals plus snacks just yet. Yes at some point introduce an evening meal, that could be now or in a months time it really depends on her interest for solids. How about just offering a few bits of finger food from your own evening meal? This would give her some practise with finger foods and you'd see if she was interested in a meal at that time.
Introducing snacks would be closer to 10-12 months really, all dependent on LO again. You don't want her milk to drop too quickly as it is still her primary food but at some point she will likely show less interest in 1 or more bottles, at that point it may be time to switch 1 milk feed (usually mid morning or mid afternoon) to a small healthy snack plus sippy cup (or whatever cup you choose) of water. This can help to keep the other 3 milk feeds intact. Later still you can switch the other day time milk for a snack. This way you keep the same timings (roughly, depending on nap times) for meals/snacks/milk but just change what you offer.
I wouldn't drop any daytime milk feeds until the night feed has gone though. My aim would be to bring her entire calorie intake to the day hours first. It's not unusual for an 8 month old to still be having a night feed, and really increasing solids in the day is unlikely to help with that, LOs get more calories/fat/nutrients from milk so it's the milk intake in the day which will reduce her need to take milk at night. You could go for a wean of the night milk if you feel ready (she'll increase her daily intake and still get the calories needed).
WRT routine, it can be tricky to fit in all those milk and solids feeds through the day but it seems you are on track, solids an hour after milk feeds is about right and shifting things slightly to fit around the naps.
If you'd like more specific help with routine times or dropping that night milk please post your current EASY.
