30 caps is what you'd often see advised as a test dose for a new pick each year or each batch to test potency, and with average caps not a long way over what I'd consider a threshold dose. Even if they're unusually strong it's not gonna be overwhelming. YMMV but I personally would expect that dose to be quite subtle: gentle breathing of walls etc, colour tints, slight patterning on surfaces and textures. If they're unusually weak it may even be disappointing. I wouldn't expect particularly brilliant CEVs at that dose for instance. You may be quite sensitive though and get to visit some quite lovely landscapes.
I'd go with tea. You'll maybe lose a little in potency, but that's compensated for by it being easier on the stomach, with a faster up, a rushier body high, and a faster, cleaner exit when you're done. Duration will be somewhat less than you'd get eating them. No bad thing for a first trial I'd suggest, peak of around 4-6 hours tops.
It's possible to intensify effects and bring up things like CEVs etc with weed, though that can darken the character of the trip and does tend to add to any confusion present, particularly during the come up as things loosen up. I would tend to advise against weed though, go for the pure, unadulterated experience. Breathing exercises and a kind of calm, meditative focus can be just as effective at enhancing effects with practice, and are very useful for anxiety. Should you experience any confusion or anxiety, try to remember it is only an effect of the drug and your ego trying to remain in control. Try not to dwell on it, or any negative thoughts that arise. Note them as an interesting effect , then just let them go. All things will pass in time if you let them. Most of all, enjoy. Have fun! Quite jealous here, first trip and all.

And you got some shrooms to play with. Not a sausage when i went out last week!
